* [SPARK-33287][SS][UI] Expose state custom metrics information on SS UI ### What changes were proposed in this pull request? Structured Streaming UI is not containing state custom metrics information. In this PR I've added it. ### Why are the changes needed? Missing state custom metrics information. ### Does this PR introduce _any_ user-facing change? Additional UI elements appear. ### How was this patch tested? Existing unit tests + manual test. ``` #Compile Spark echo "spark.sql.streaming.ui.enabledCustomMetricList stateOnCurrentVersionSizeBytes" >> conf/spark-defaults.conf sbin/start-master.sh sbin/start-worker.sh spark://gsomogyi-MBP16:7077 ./bin/spark-submit --master spark://gsomogyi-MBP16:7077 --deploy-mode client --class com.spark.Main ../spark-test/target/spark-test-1.0-SNAPSHOT-jar-with-dependencies.jar ``` <img width="1119" alt="Screenshot 2020-11-18 at 12 45 36" src="https://user-images.githubusercontent.com/18561820/99527506-2f979680-299d-11eb-9187-4ae7fbd2596a.png"> Closes #30336 from gaborgsomogyi/SPARK-33287.

This pull request: - Adds following flags to the main mypy configuration: - [`strict_optional`](https://mypy.readthedocs.io/en/stable/config_file.html#confval-strict_optional) - [`no_implicit_optional`](https://mypy.readthedocs.io/en/stable/config_file.html#confval-no_implicit_optional) - [`disallow_untyped_defs`](https://mypy.readthedocs.io/en/stable/config_file.html#confval-disallow_untyped_calls) These flags are enabled only for public API and disabled for tests and internal modules. Additionally, these PR fixes missing annotations. ### Why are the changes needed? Primary reason to propose this changes is to use standard configuration as used by typeshed project. This will allow us to be more strict, especially when interacting with JVM code. See for example https://github.com/apache/spark/pull/29122#pullrequestreview-513112882 Additionally, it will allow us to detect cases where annotations have unintentionally omitted. ### Does this PR introduce _any_ user-facing change?

This PR proposes to migrate `SHOW COLUMNS` to use `UnresolvedTableOrView` to resolve the table/view identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing). Note that `SHOW COLUMNS` is not yet supported for v2 tables. ### Why are the changes needed? To use `UnresolvedTableOrView` for table/view resolution. Note that `ShowColumnsCommand` internally resolves to a temp view first, so there is no resolution behavior change with this PR. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Updated existing tests. Closes #30490 from imback82/show_columns.

This PR proposes to add the watermark gap information in SS UI page. Please refer below screenshots to see what we'd like to show in UI.  Please note that this PR doesn't plot the watermark value - knowing the gap between actual wall clock and watermark looks more useful than the absolute value. ### Why are the changes needed? Watermark is the one of major metrics the end users need to track for stateful queries. Watermark defines "when" the output will be emitted for append mode, hence knowing how much gap between wall clock and watermark (input data) is very helpful to make expectation of the output. ### Does this PR introduce _any_ user-facing change? Yes, SS UI query page will contain the watermark gap information. ### How was this patch tested? Basic UT added. Manually tested with two queries: > simple case You'll see consistent watermark gap with (15 seconds + a) = 10 seconds are from delay in watermark definition, 5 seconds are trigger interval. ``` import org.apache.spark.sql.streaming.Trigger spark.conf.set("spark.sql.shuffle.partitions", "10") val query = spark .readStream .format("rate") .option("rowsPerSecond", 1000) .option("rampUpTime", "10s") .load() .selectExpr("timestamp", "mod(value, 100) as mod", "value") .withWatermark("timestamp", "10 seconds") .groupBy(window($"timestamp", "1 minute", "10 seconds"), $"mod") .agg(max("value").as("max_value"), min("value").as("min_value"), avg("value").as("avg_value")) .writeStream .format("console") .trigger(Trigger.ProcessingTime("5 seconds")) .outputMode("append") .start() query.awaitTermination() ```  > complicated case This randomizes the timestamp, hence producing random watermark gap. This won't be smaller than 15 seconds as I described earlier. ``` import org.apache.spark.sql.streaming.Trigger spark.conf.set("spark.sql.shuffle.partitions", "10") val query = spark .readStream .format("rate") .option("rowsPerSecond", 1000) .option("rampUpTime", "10s") .load() .selectExpr("*", "CAST(CAST(timestamp AS BIGINT) - CAST((RAND() * 100000) AS BIGINT) AS TIMESTAMP) AS tsMod") .selectExpr("tsMod", "mod(value, 100) as mod", "value") .withWatermark("tsMod", "10 seconds") .groupBy(window($"tsMod", "1 minute", "10 seconds"), $"mod") .agg(max("value").as("max_value"), min("value").as("min_value"), avg("value").as("avg_value")) .writeStream .format("console") .trigger(Trigger.ProcessingTime("5 seconds")) .outputMode("append") .start() query.awaitTermination() ```  Closes #30427 from HeartSaVioR/SPARK-33224.

Remove SQL configuration spark.sql.legacy.allowCastNumericToTimestamp ### Why are the changes needed? In the current master branch, there is a new configuration `spark.sql.legacy.allowCastNumericToTimestamp` which controls whether to cast Numeric types to Timestamp or not. The default value is true. After https://github.com/apache/spark/pull/30260, the type conversion between Timestamp type and Numeric type is disallowed in ANSI mode. So, we don't need to a separate configuration `spark.sql.legacy.allowCastNumericToTimestamp` for disallowing the conversion. Users just need to set `spark.sql.ansi.enabled` for the behavior. As the configuration is not in any released yet, we should remove the configuration to make things simpler. ### Does this PR introduce _any_ user-facing change? No, since the configuration is not released yet. ### How was this patch tested? Existing test cases Closes #30493 from gengliangwang/LEGACY_ALLOW_CAST_NUMERIC_TO_TIMESTAMP.

Add new method `listPartitionByNames` to the `SupportsPartitionManagement` interface. It allows to list partitions by partition names and their values. 2. Implement new method in `InMemoryPartitionTable` which is used in DSv2 tests. ### Why are the changes needed? Currently, the `SupportsPartitionManagement` interface exposes only `listPartitionIdentifiers` which allows to list partitions by partition values. And it requires to specify all values for partition schema fields in the prefix. This restriction does not allow to list partitions by some of partition names (not all of them). For example, the table `tableA` is partitioned by two column `year` and `month` ``` CREATE TABLE tableA (price int, year int, month int) USING _ partitioned by (year, month) ``` and has the following partitions: ``` PARTITION(year = 2015, month = 1) PARTITION(year = 2015, month = 2) PARTITION(year = 2016, month = 2) PARTITION(year = 2016, month = 3) ``` If we want to list all partitions with `month = 2`, we have to specify `year` for **listPartitionIdentifiers()** which not always possible as we don't know all `year` values in advance. New method **listPartitionByNames()** allows to specify partition values only for `month`, and get two partitions: ``` PARTITION(year = 2015, month = 2) PARTITION(year = 2016, month = 2) ``` ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? By running the affected test suite `SupportsPartitionManagementSuite`. Closes #30452 from MaxGekk/column-names-listPartitionIdentifiers.

When using dynamic partition overwrite, each task has its working dir under staging dir like `stagingDir/.spark-staging-{jobId}`, each task commits to `outputPath/.spark-staging-{jobId}/{partitionId}/part-{taskId}-{jobId}{ext}`. When speculation enable, multiple task attempts would be setup for one task, **they have same task id and they would commit to same file concurrently**. Due to host done or node preemption, the partly-committed files aren't cleaned up, a FileAlreadyExistsException would be raised in this situation, resulting in job failure. I don't try to change task commit process for dynamic partition overwrite, like adding attempt id to task working dir for each attempts and committing to final output dir via a new outputCommitCoordinator, here is reason: 1. `FileOutputCommitter` already has commit coordinator for each task attempts, we can leverage it rather than build a new one. 2. To say the least, we implement a coordinator solving task attempts commit conflict, suppose a severe case, application master failover, tasks with same attempt id and same task id would commit to same files, the `FileAlreadyExistsException` risk still exists In this pr, I leverage FileOutputCommitter to solve the problem: 1. when initing a write job description, set `outputPath/.spark-staging-{jobId}` as the output dir 2. each task attempt writes output to `outputPath/.spark-staging-{jobId}/_temporary/${appAttemptId}/_temporary/${taskAttemptId}/{partitionId}/part-{taskId}-{jobId}{ext}` 3. leverage `FileOutputCommitter` coordinator, write job firstly commits output to `outputPath/.spark-staging-{jobId}/{partitionId}` 4. for dynamic partition overwrite, write job finally move `outputPath/.spark-staging-{jobId}/{partitionId}` to `outputPath/{partitionId}` ### Why are the changes needed? Without this pr, dynamic partition overwrite would fail ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? added UT.

This PR fixes an AQE issue where local shuffle reader, partition coalescing, or skew join optimization can be mistakenly applied to a shuffle introduced by repartition or a regular shuffle that logically replaces a repartition shuffle. The proposed solution checks for the presence of any repartition shuffle and filters out not applicable optimization rules for the final stage in an AQE plan. ### Why are the changes needed?

There are some differences between Spark CSV, opencsv and commons-csv, the typical case are described in SPARK-33566, When there are both unescaped quotes and unescaped qualifier in value, the results of parsing are different. The reason for the difference is Spark use `STOP_AT_DELIMITER` as default `UnescapedQuoteHandling` to build `CsvParser` and it not configurable. On the other hand, opencsv and commons-csv use the parsing mechanism similar to `STOP_AT_CLOSING_QUOTE ` by default. So this pr make `unescapedQuoteHandling` option configurable to get the same parsing result as opencsv and commons-csv. ### Why are the changes needed?

Currently in Spark one could redefine a window. For instance: `select count(*) OVER w FROM tenk1 WINDOW w AS (ORDER BY unique1), w AS (ORDER BY unique1);` The window `w` is defined two times. In PgSQL, on the other hand, a thrown will happen: `ERROR: window "w" is already defined` ### Why are the changes needed? The current implement gives the following window definitions a higher priority. But it wasn't Spark's intention and users can't know from any document of Spark.

This PR changes mariadb_docker_entrypoint.sh to set the proper version automatically for mariadb-plugin-gssapi-server. The proper version is based on the one of mariadb-server. Also, this PR enables to use arbitrary docker image by setting the environment variable `MARIADB_CONTAINER_IMAGE_NAME`. ### Why are the changes needed? For `MariaDBKrbIntegrationSuite`, the version of `mariadb-plugin-gssapi-server` is currently set to `10.5.5` in `mariadb_docker_entrypoint.sh` but it's no longer available in the official apt repository and `MariaDBKrbIntegrationSuite` doesn't pass for now. It seems that only the most recent three versions are available for each major version and they are `10.5.6`, `10.5.7` and `10.5.8` for now. Further, the release cycle of MariaDB seems to be very rapid (1 ~ 2 months) so I don't think it's a good idea to set to an specific version for `mariadb-plugin-gssapi-server`. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Confirmed that `MariaDBKrbIntegrationSuite` passes with the following commands. ``` $ build/sbt -Pdocker-integration-tests -Phive -Phive-thriftserver package "testOnly org.apache.spark.sql.jdbc.MariaDBKrbIntegrationSuite" ``` In this case, we can see what version of `mariadb-plugin-gssapi-server` is going to be installed in the following container log message. ``` Installing mariadb-plugin-gssapi-server=1:10.5.8+maria~focal ``` Or, we can set MARIADB_CONTAINER_IMAGE_NAME for a specific version of MariaDB. ``` $ MARIADB_DOCKER_IMAGE_NAME=mariadb:10.5.6 build/sbt -Pdocker-integration-tests -Phive -Phive-thriftserver package "testOnly org.apache.spark.sql.jdbc.MariaDBKrbIntegrationSuite" ``` ``` Installing mariadb-plugin-gssapi-server=1:10.5.6+maria~focal ``` Closes #30515 from sarutak/fix-MariaDBKrbIntegrationSuite.

However, if the fatal error is wrapped by another exception, such as - java.util.concurrent.ExecutionException, com.google.common.util.concurrent.UncheckedExecutionException, com.google.common.util.concurrent.ExecutionError when using Guava cache or Java thread pool. - SparkException thrown from https://github.com/apache/spark/blob/cf98a761de677c733f3c33230e1c63ddb785d5c5/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/FileFormatWriter.scala#L231 or https://github.com/apache/spark/blob/cf98a761de677c733f3c33230e1c63ddb785d5c5/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/FileFormatWriter.scala#L296 We will still keep the executor running. Fatal errors are usually unrecoverable (such as OutOfMemoryError), some components may be in a broken state when hitting a fatal error and it's hard to predicate the behaviors of a broken component.

Perform partition spec normalization in `ShowTablesCommand` according to the table schema before getting partitions from the catalog. The normalization via `PartitioningUtils.normalizePartitionSpec()` adjusts the column names in partition specification, w.r.t. the real partition column names and case sensitivity. ### Why are the changes needed? Even when `spark.sql.caseSensitive` is `false` which is the default value, v1 `SHOW TABLE EXTENDED` is case sensitive: ```sql spark-sql> CREATE TABLE tbl1 (price int, qty int, year int, month int) > USING parquet > partitioned by (year, month); spark-sql> INSERT INTO tbl1 PARTITION(year = 2015, month = 1) SELECT 1, 1; spark-sql> SHOW TABLE EXTENDED LIKE 'tbl1' PARTITION(YEAR = 2015, Month = 1); Error in query: Partition spec is invalid. The spec (YEAR, Month) must match the partition spec (year, month) defined in table '`default`.`tbl1`'; ``` ### Does this PR introduce _any_ user-facing change? Yes.

[identifierList] ... * INSERT INTO [TABLE] tableIdentifier [partitionSpec] [identifierList] ... * }}} */ ``` The column list represents all expected columns with an explicit order that you want to insert to the target table. **Particularly**, we assume the column list contains all the column names in the current implementation, it will fail when the list is incomplete. In **Analyzer**, we add a code path to resolve the column list in the `ResolveOutputRelation` rule before it is transformed to v1 or v2 command. It will fail here if the list has any field that not belongs to the target table. Then, for v2 command, e.g. `AppendData`, we use the resolved column list and output of the target table to resolve the output of the source query `ResolveOutputRelation` rule. If the list has duplicated columns, we fail. If the list is not empty but the list size does not match the target table, we fail. If no other exceptions occur, we use the column list to map the output of the source query to the output of the target table. The column list will be set to Nil and it will not hit the rule again after it is resolved. for v1 command, those all happen in the `PreprocessTableInsertion` rule ### Why are the changes needed? new feature support ### Does this PR introduce _any_ user-facing change? yes, insert into/overwrite table support specify column list ### How was this patch tested? new tests Closes #29893 from yaooqinn/SPARK-32976. Authored-by: Kent Yao <[email protected]> Signed-off-by: Wenchen Fan <[email protected]> * [SPARK-33448][SQL] Support CACHE/UNCACHE TABLE commands for v2 tables ### What changes were proposed in this pull request? This PR proposes to support `CHACHE/UNCACHE TABLE` commands for v2 tables. In addtion, this PR proposes to migrate `CACHE/UNCACHE TABLE` to use `UnresolvedTableOrView` to resolve the table identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing). ### Why are the changes needed? To support `CACHE/UNCACHE TABLE` commands for v2 tables. Note that `CACHE/UNCACHE TABLE` for v1 tables/views go through `SparkSession.table` to resolve identifier, which resolves temp views first, so there is no change in the behavior by moving to the new framework. ### Does this PR introduce _any_ user-facing change? Yes. Now the user can run `CACHE/UNCACHE TABLE` commands on v2 tables. ### How was this patch tested? Added/updated existing tests. Closes #30403 from imback82/cache_table.

Currently, Spark allows calls to `count` even for non parameterless aggregate function. For example, the following query actually works: `SELECT count() FROM tenk1;` On the other hand, mainstream databases will throw an error. **Oracle** `> ORA-00909: invalid number of arguments` **PgSQL** `ERROR: count(*) must be used to call a parameterless aggregate function` **MySQL** `> 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')` ### Why are the changes needed? Fix a bug so that consistent with mainstream databases. There is an example query output with/without this fix. `SELECT count() FROM testData;` The output before this fix: `0` The output after this fix: ``` org.apache.spark.sql.AnalysisException cannot resolve 'count()' due to data type mismatch: count requires at least one argument.; line 1 pos 7 ``` ### Does this PR introduce _any_ user-facing change? Yes. If not specify parameter for `count`, will throw an error. ### How was this patch tested? Jenkins test. Closes #30541 from beliefer/SPARK-28646.

This PR adds the char/varchar type which is kind of a variant of string type: 1. Char type is fixed-length string. When comparing char type values, we need to pad the shorter one to the longer length. 2. Varchar type is string with a length limitation. To implement the char/varchar semantic, this PR: 1. Do string length check when writing to char/varchar type columns. 2. Do string padding when reading char type columns. We don't do it at the writing side to save storage space. 3. Do string padding when comparing char type column with string literal or another char type column. (string literal is fixed length so should be treated as char type as well) To simplify the implementation, this PR doesn't propagate char/varchar type info through functions/operator…
