* [SPARK-4180] [Core] Prevent creation of multiple active SparkContextsJosh Rosen2014-11-172-102/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds error-detection logic to throw an exception when attempting to create multiple active SparkContexts in the same JVM, since this is currently unsupported and has been known to cause confusing behavior (see SPARK-2243 for more details). **The solution implemented here is only a partial fix.** A complete fix would have the following properties: 1. Only one SparkContext may ever be under construction at any given time. 2. Once a SparkContext has been successfully constructed, any subsequent construction attempts should fail until the active SparkContext is stopped. 3. If the SparkContext constructor throws an exception, then all resources created in the constructor should be cleaned up (SPARK-4194). 4. If a user attempts to create a SparkContext but the creation fails, then the user should be able to create new SparkContexts. This PR only provides 2) and 4); we should be able to provide all of these properties, but the correct fix will involve larger changes to SparkContext's construction / initialization, so we'll target it for a different Spark release. ### The correct solution: I think that the correct way to do this would be to move the construction of SparkContext's dependencies into a static method in the SparkContext companion object. Specifically, we could make the default SparkContext constructor `private` and change it to accept a `SparkContextDependencies` object that contains all of SparkContext's dependencies (e.g. DAGScheduler, ContextCleaner, etc.). Secondary constructors could call a method on the SparkContext companion object to create the `SparkContextDependencies` and pass the result to the primary SparkContext constructor. For example: ```scala class SparkContext private (deps: SparkContextDependencies) { def this(conf: SparkConf) { this(SparkContext.getDeps(conf)) } } object SparkContext( private[spark] def getDeps(conf: SparkConf): SparkContextDependencies = synchronized { if (anotherSparkContextIsActive) { throw Exception(...) } var dagScheduler: DAGScheduler = null try { dagScheduler = new DAGScheduler(...) [...] } catch { case e: Exception => Option(dagScheduler).foreach(_.stop()) [...] } SparkContextDependencies(dagScheduler, ....) } } ``` This gives us mutual exclusion and ensures that any resources created during the failed SparkContext initialization are properly cleaned up. This indirection is necessary to maintain binary compatibility. In retrospect, it would have been nice if SparkContext had no private constructors and could only be created through builder / factory methods on its companion object, since this buys us lots of flexibility and makes dependency injection easier. ### Alternative solutions: As an alternative solution, we could refactor SparkContext's primary constructor to perform all object creation in a giant `try-finally` block. Unfortunately, this will require us to turn a bunch of `vals` into `vars` so that they can be assigned from the `try` block. If we still want `vals`, we could wrap each `val` in its own `try` block (since the try block can return a value), but this will lead to extremely messy code and won't guard against the introduction of future code which doesn't properly handle failures. The more complex approach outlined above gives us some nice dependency injection benefits, so I think that might be preferable to a `var`-ification. ### This PR's solution: - At the start of the constructor, check whether some other SparkContext is active; if so, throw an exception. - If another SparkContext might be under construction (or has thrown an exception during construction), allow the new SparkContext to begin construction but log a warning (since resources might have been leaked from a failed creation attempt). - At the end of the SparkContext constructor, check whether some other SparkContext constructor has raced and successfully created an active context. If so, throw an exception. This guarantees that no two SparkContexts will ever be active and exposed to users (since we check at the very end of the constructor). If two threads race to construct SparkContexts, then one of them will win and another will throw an exception. This exception can be turned into a warning by setting `spark.driver.allowMultipleContexts = true`. The exception is disabled in unit tests, since there are some suites (such as Hive) that may require more significant refactoring to clean up their SparkContexts. I've made a few changes to other suites' test fixtures to properly clean up SparkContexts so that the unit test logs contain fewer warnings.

* [SPARK-4301] StreamingContext should not allow start() to be called after ↵Josh Rosen2014-11-082-23/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | calling stop() In Spark 1.0.0+, calling `stop()` on a StreamingContext that has not been started is a no-op which has no side-effects. This allows users to call `stop()` on a fresh StreamingContext followed by `start()`. I believe that this almost always indicates an error and is not behavior that we should support. Since we don't allow `start() stop() start()` then I don't think it makes sense to allow `stop() start()`. The current behavior can lead to resource leaks when StreamingContext constructs its own SparkContext: if I call `stop(stopSparkContext=True)`, then I expect StreamingContext's underlying SparkContext to be stopped irrespective of whether the StreamingContext has been started. This is useful when writing unit test fixtures.

* [SPARK-4029][Streaming] Update streaming driver to reliably save and recover ↵Tathagata Das2014-11-058-89/+597
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | received block metadata on driver failures As part of the initiative of preventing data loss on driver failure, this JIRA tracks the sub task of modifying the streaming driver to reliably save received block metadata, and recover them on driver restart. This was solved by introducing a `ReceivedBlockTracker` that takes all the responsibility of managing the metadata of received blocks (i.e. `ReceivedBlockInfo`, and any actions on them (e.g, allocating blocks to batches, etc.). All actions to block info get written out to a write ahead log (using `WriteAheadLogManager`). On recovery, all the actions are replaying to recreate the pre-failure state of the `ReceivedBlockTracker`, which include the batch-to-block allocations and the unallocated blocks. Furthermore, the `ReceiverInputDStream` was modified to create `WriteAheadLogBackedBlockRDD`s when file segment info is present in the `ReceivedBlockInfo`. After recovery of all the block info (through recovery `ReceivedBlockTracker`), the `WriteAheadLogBackedBlockRDD`s gets recreated with the recovered info, and jobs submitted. The data of the blocks gets pulled from the write ahead logs, thanks to the segment info present in the `ReceivedBlockInfo`. This is still a WIP. Things that are missing here are. - *End-to-end integration tests:* Unit tests that tests the driver recovery, by killing and restarting the streaming context, and verifying all the input data gets processed. This has been implemented but not included in this PR yet. A sneak peek of that DriverFailureSuite can be found in this PR (on my personal repo): https://github.com/tdas/spark/pull/25 I can either include it in this PR, or submit that as a separate PR after this gets in. - *WAL cleanup:* Cleaning up the received data write ahead log, by calling `ReceivedBlockHandler.cleanupOldBlocks`. This is being worked on.

| | | | | | | | | | | | | | | | | If classes implementing Serializable or Externalizable interfaces throw exceptions other than IOException or ClassNotFoundException from their (de)serialization methods, then this results in an unhelpful "IOException: unexpected exception type" rather than the actual exception that produced the (de)serialization error. This patch fixes this by adding a utility method that re-wraps any uncaught exceptions in IOException (unless they are already instances of IOException).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of the effort to avoid data loss on Spark Streaming driver failure, we want to implement a write ahead log that can write received data to HDFS. This allows the received data to be persist across driver failures. So when the streaming driver is restarted, it can find and reprocess all the data that were received but not processed. This was primarily implemented by @harishreedharan. This is still WIP, as he is going to improve the unitests by using HDFS mini cluster.

* [SPARK-2805] Upgrade Akka to 2.3.4Anand Avati2014-10-101-71/+0
| | | | | | | | | | | | | This is a second rev of the Akka upgrade (earlier merged, but reverted). I made a slight modification which is that I also upgrade Hive to deal with a compatibility issue related to the protocol buffers library. Author: Anand Avati <avati@redhat.com> Author: Patrick Wendell <pwendell@gmail.com> Closes #2752 from pwendell/akka-upgrade and squashes the following commits: 4c7ca3f [Patrick Wendell] Upgrading to new hive->protobuf version 57a2315 [Anand Avati] SPARK-1812: streaming - remove tests which depend on akka.actor.IO 2a551d3 [Anand Avati] SPARK-1812: core - upgrade to akka 2.3.4
* SPARK-3811 [CORE] More robust / standard Utils.deleteRecursively, ↵Sean Owen2014-10-094-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Utils.createTempDir I noticed a few issues with how temp directories are created and deleted: *Minor* * Guava's `Files.createTempDir()` plus `File.deleteOnExit()` is used in many tests to make a temp dir, but `Utils.createTempDir()` seems to be the standard Spark mechanism * Call to `File.deleteOnExit()` could be pushed into `Utils.createTempDir()` as well, along with this replacement * _I messed up the message in an exception in `Utils` in SPARK-3794; fixed here_ *Bit Less Minor* * `Utils.deleteRecursively()` fails immediately if any `IOException` occurs, instead of trying to delete any remaining files and subdirectories. I've observed this leave temp dirs around. I suggest changing it to continue in the face of an exception and throw one of the possibly several exceptions that occur at the end. * `Utils.createTempDir()` will add a JVM shutdown hook every time the method is called. Even if the subdir is the parent of another parent dir, since this check is inside the hook. However `Utils` manages a set of all dirs to delete on shutdown already, called `shutdownDeletePaths`. A single hook can be registered to delete all of these on exit. This is how Tachyon temp paths are cleaned up in `TachyonBlockManager`. I noticed a few other things that might be changed but wanted to ask first: * Shouldn't the set of dirs to delete be `File`, not just `String` paths? * `Utils` manages the set of `TachyonFile` that have been registered for deletion, but the shutdown hook is managed in `TachyonBlockManager`. Should this logic not live together, and not in `Utils`? it's more specific to Tachyon, and looks a slight bit odd to import in such a generic place. Author: Sean Owen <sowen@cloudera.com> Closes #2670 from srowen/SPARK-3811 and squashes the following commits: 071ae60 [Sean Owen] Update per @vanzin's review da0146d [Sean Owen] Make Utils.deleteRecursively try to delete all paths even when an exception occurs; use one shutdown hook instead of one per method call to delete temp dirs 3a0faa4 [Sean Owen] Standardize on Utils.createTempDir instead of Files.createTempDir
