[SPARK-25339][TEST] Refactor FilterPushdownBenchmark #22443

wangyum · 2018-09-17T17:08:05Z

What changes were proposed in this pull request?

Refactor FilterPushdownBenchmark use main method. we can use 3 ways to run this test now:

bin/spark-submit --class org.apache.spark.sql.execution.benchmark.FilterPushdownBenchmark spark-sql_2.11-2.5.0-SNAPSHOT-tests.jar
build/sbt "sql/test:runMain org.apache.spark.sql.execution.benchmark.FilterPushdownBenchmark"
SPARK_GENERATE_BENCHMARK_FILES=1 build/sbt "sql/test:runMain org.apache.spark.sql.execution.benchmark.FilterPushdownBenchmark"

The method 2 and the method 3 do not need to compile the spark-sql_*-tests.jar package. So these two methods are mainly for developers to quickly do benchmark.

How was this patch tested?

manual tests

Thank you for your swift PR, @wangyum ! I'll take a look tonight. BTW, could you update the title [TESTS] into [TEST] because [TEST] is simpler and more popular from the Spark log?

dongjoon-hyun · 2018-09-17T18:52:01Z

2 and 3 are possible and convenient as you mentioned. But, we are trying to avoid 2 and 3, aren't we?

2. build/sbt "sql/test:runMain org.apache.spark.sql.execution.benchmark.FilterPushdownBenchmark"
3. SPARK_GENERATE_BENCHMARK_FILES=1 build/sbt "sql/test:runMain org.apache.spark.sql.execution.benchmark.FilterPushdownBenchmark"

Please correct me if I'm wrong, @cloud-fan .

sql/core/src/test/scala/org/apache/spark/sql/execution/benchmark/FilterPushdownBenchmark.scala

+ * To run this benchmark:
+ *  1. without sbt: bin/spark-submit --class <this class> <spark sql test jar>
+ *  2. build/sbt "sql/test:runMain <this class>"
+ *  3. generate result: SPARK_GENERATE_BENCHMARK_FILES=1 build/sbt "sql/test:runMain <this class>"


shall we print the benchmark result if SPARK_GENERATE_BENCHMARK_FILES is not set?

IIRC there is a special OutputStream that can print the output to console.

Yes, It can print the output to console if SPARK_GENERATE_BENCHMARK_FILES not set.

spark/core/src/main/scala/org/apache/spark/util/Benchmark.scala

Lines 59 to 63 in 4e8ac6e

val out = if (output.isDefined) {

new PrintStream(new TeeOutputStream(System.out, output.get))

} else {

System.out

}

nit: remove the one space indent before the numbered list

@dongjoon-hyun we are trying to avoid the overhead of scalatest, not sbt. So this LGTM

dongjoon-hyun · 2018-09-18T09:47:55Z

Thank you for confirmation, @cloud-fan .

thanks, merging to master!

@dongjoon-hyun Can you create an umbrella JIRA for updating all the benchmark and take care of it? Thanks!

dongjoon-hyun · 2018-09-20T04:39:10Z

I see, @cloud-fan .

dongjoon-hyun · 2018-09-20T05:24:51Z

https://issues.apache.org/jira/browse/SPARK-25475 is created.

dongjoon-hyun · 2018-09-20T05:30:33Z

@gengliangwang . SPARK-25475 is created like the above, could you revise #22451 in order print the output as a separate file like this PR?

gengliangwang · 2018-09-20T06:09:14Z

@dongjoon-hyun No problem. I was waiting for this PR to be merged.

dongjoon-hyun · 2018-09-20T06:19:05Z

Thank you, @gengliangwang !

+      if (!file.exists()) {
+        file.createNewFile()
+      }
+      output = Some(new FileOutputStream(file))


nit: try-catch and close it.

nit: Option(new FileOutputStream(file)) and remove if (o != null) { below.

Please address them when you fix some codes around here next time.

Thanks @HyukjinKwon. Will fix it next time.
