Kernel 2.6.32 bug will lead to unexpected behavior of transferTo in copyStream, and this will corrupt the shuffle output file in sort-based shuffle, which will somehow introduce PARSING_ERROR(2), deserialization error or offset out of range. Here fix this by adding append flag, also add some position checking code. Details can be seen in [SPARK-3948](https://issues.apache.org/jira/browse/SPARK-3948).

Before, if the master node is killed and restarted, the worker nodes would not attempt to reconnect to the Master. Therefore, when the Master node was restarted, the worker nodes needed to be restarted as well. Now, when the Master node is disconnected, the worker nodes will continuously ping the master node in attempts to reconnect to it. Once the master node restarts, it will detect one of the registration requests from its former workers. The result is that the cluster re-enters a healthy state. In addition, when the master does not receive a heartbeat from the worker, the worker was removed; however, when the worker sent a heartbeat to the master, the master used to ignore the heartbeat. Now, a master that receives a heartbeat from a worker that had been disconnected will request the worker to re-attempt the registration process, at which point the worker will send a RegisterWorker request and be re-connected accordingly. Re-connection attempts per worker are submitted every N seconds, where N is configured by the property spark.worker.reconnect.interval - this has a default of 60 seconds right now.

…ree more adaptively DecisionTree splits on continuous features by choosing an array of values from a subsample of the data. Currently, it does not check for identical values in the subsample, so it could end up having multiple copies of the same split. In this PR, we choose splits for a continuous feature in 3 steps: 1. Sort sample values for this feature 2. Get number of occurrence of each distinct value 3. Iterate the value count array computed in step 2 to choose splits. After find splits, `numSplits` and `numBins` in metadata will be updated. CC: mengxr manishamde jkbradley, please help me review this, thanks.

This PR makes several changes to TorrentBroadcast in order to make it easier to reason about, which should help when debugging SPARK-3958. The key changes: - Remove all state from the global TorrentBroadcast object. This state consisted mainly of configuration options, like the block size and compression codec, and was read by the blockify / unblockify methods. Unfortunately, the use of `lazy val` for `BLOCK_SIZE` meant that the block size was always determined by the first SparkConf that TorrentBroadast was initialized with; as a result, unit tests could not properly test TorrentBroadcast with different block sizes. Instead, blockifyObject and unBlockifyObject now accept compression codecs and blockSizes as arguments. These arguments are supplied at the call sites inside of TorrentBroadcast instances. Each TorrentBroadcast instance determines these values from SparkEnv's SparkConf. I was careful to ensure that we do not accidentally serialize CompressionCodec or SparkConf objects as part of the TorrentBroadcast object. - Remove special-case handling of local-mode in TorrentBroadcast. I don't think that broadcast implementations should know about whether we're running in local mode. If we want to optimize the performance of broadcast in local mode, then we should detect this at a higher level and use a dummy LocalBroadcastFactory implementation instead. Removing this code fixes a subtle error condition: in the old local mode code, a failure to find the broadcast in the local BlockManager would lead to an attempt to deblockify zero blocks, which could lead to confusing deserialization or decompression errors when we attempted to decompress an empty byte array. This should never have happened, though: a failure to find the block in local mode is evidence of some other error. The changes here will make it easier to debug those errors if they ever happen. - Add a check that throws an exception when attempting to deblockify an empty array. - Use ScalaCheck to add a test to check that TorrentBroadcast's blockifyObject and unBlockifyObject methods are inverses. - Misc. cleanup and logging improvements.

If an executor fails without being scheduled to run any tasks, then `DAGScheduler` won't notify `BlockManagerMasterActor` that the associated block manager should be removed. Instead, the associated block manager will be expired only after a few rounds of heartbeat timeouts. In terms of removal treatment, there should really be no distinction between executors that have been scheduled tasks and those that have not. The fix, then, is to add all known executors to `TaskSchedulerImpl`'s `activeExecutorIds` whether or not it has been scheduled a task. In fact, the existing comment above `activeExecutorIds` is ``` // Which executor IDs we have executors on val activeExecutorIds = new HashSet[String] ``` not "Which executors have been scheduled tasks thus far."

… and spark.shuffle.spill.compress settings are different This PR fixes SPARK-3426, an issue where sort-based shuffle crashes if the `spark.shuffle.spill.compress` and `spark.shuffle.compress` settings have different values. The problem is that sort-based shuffle's read and write paths use different settings for determining whether to apply compression. ExternalSorter writes runs to files using `TempBlockId` ids, which causes `spark.shuffle.spill.compress` to be used for enabling compression, but these spilled files end up being shuffled over the network and read as shuffle files using `ShuffleBlockId` by BlockStoreShuffleFetcher, which causes `spark.shuffle.compress` to be used for enabling decompression. As a result, this leads to errors when these settings disagree. Based on the discussions in #2247 and #2178, it sounds like we don't want to remove the `spark.shuffle.spill.compress` setting. Therefore, I've tried to come up with a fix where `spark.shuffle.spill.compress` is used to compress data that's read and written locally and `spark.shuffle.compress` is used to compress any data that will be fetched / read as shuffle blocks. To do this, I split `TempBlockId` into two new id types, `TempLocalBlockId` and `TempShuffleBlockId`, which map to `spark.shuffle.spill.compress` and `spark.shuffle.compress`, respectively. ExternalAppendOnlyMap also used temp blocks for spilling data. It looks like ExternalSorter was designed to be a generic sorter but its configuration already happens to be tied to sort-based shuffle, so I think it's fine if we use `spark.shuffle.compress` to compress its spills; we can move the compression configuration to the constructor in a later commit if we find that ExternalSorter is being used in other contexts where we want different configuration options to control compression. To summarize: **Before:** | | ExternalAppendOnlyMap | ExternalSorter | |-------|------------------------------|------------------------------| | Read | spark.shuffle.spill.compress | spark.shuffle.compress | | Write | spark.shuffle.spill.compress | spark.shuffle.spill.compress | **After:** | | ExternalAppendOnlyMap | ExternalSorter | |-------|------------------------------|------------------------| | Read | spark.shuffle.spill.compress | spark.shuffle.compress | | Write | spark.shuffle.spill.compress | spark.shuffle.compress | Thanks to andrewor14 for debugging this with me!

This patch will try to infer schema for RDD which has empty value (None, [], {}) in the first row. It will try first 100 rows and merge the types into schema, also merge fields of StructType together. If there is still NullType in schema, then it will show an warning, tell user to try with sampling.
If sampling is presented, it will infer schema from all the rows after sampling.
Also, add samplingRatio for jsonFile() and jsonRDD()

This feature is based on an offline discussion with mengxr, hopefully can be useful for the new MLlib pipeline API.
For the following test snippet
```scala
case class KeyValue(key: Int, value: String)
val testData = sc.parallelize(1 to 10).map(i => KeyValue(i, i.toString)).toSchemaRDD
def foo(a: Int, b: String) => a.toString + b
```
the newly introduced DSL enables the following syntax
```scala
import org.apache.spark.sql.catalyst.dsl._
testData.select(Star(None), foo.call('key, 'value) as 'result)
```
which is equivalent to
```scala
testData.registerTempTable("testData")
sqlContext.registerFunction("foo", foo)
sql("SELECT *, foo(key, value) AS result FROM testData")
```

This patch allows executor thread dumps to be collected on-demand and viewed in the Spark web UI. The thread dumps are collected using Thread.getAllStackTraces(). To allow remote thread dumps to be triggered from the web UI, I added a new `ExecutorActor` that runs inside of the Executor actor system and responds to RPCs from the driver. The driver's mechanism for obtaining a reference to this actor is a little bit hacky: it uses the block manager master actor to determine the host/port of the executor actor systems in order to construct ActorRefs to ExecutorActor. Unfortunately, I couldn't find a much cleaner way to do this without a big refactoring of the executor -> driver communication.

Following #2919, this PR adds Python UDT (for internal use only) with tests under "pyspark.tests". Before `SQLContext.applySchema`, we check whether we need to convert user-type instances into SQL recognizable data.
