* [SPARK-3128][MLLIB] Use streaming test suite for StreamingLRfreeman2014-08-191-1/+3
| | | | | | | | | | | | | | | | | | | Refactored tests for streaming linear regression to use existing streaming test utilities. Summary of changes: - Made ``mllib`` depend on tests from ``streaming`` - Rewrote accuracy and convergence tests to use ``setupStreams`` and ``runStreams`` - Added new test for the accuracy of predictions generated by ``predictOnValue`` These tests should run faster, be easier to extend/maintain, and provide a reference for new tests. mengxr tdas Author: freeman <the.freeman.lab@gmail.com> Closes #2037 from freeman-lab/streamingLR-predict-tests and squashes the following commits: e851ca7 [freeman] Fixed long lines 50eb0bf [freeman] Refactored tests to use streaming test tools 32c43c2 [freeman] Added test for prediction

* SPARK-1798. Tests should clean up temp filesSean Owen2014-05-124-2/+8
| | | | | | | | | | | | | | | | | | | | Three issues related to temp files that tests generate – these should be touched up for hygiene but are not urgent. Modules have a log4j.properties which directs the unit-test.log output file to a directory like `[module]/target/unit-test.log`. But this ends up creating `[module]/[module]/target/unit-test.log` instead of former. The `work/` directory is not deleted by "mvn clean", in the parent and in modules. Neither is the `checkpoint/` directory created under the various external modules. Many tests create a temp directory, which is not usually deleted. This can be largely resolved by calling `deleteOnExit()` at creation and trying to call `Utils.deleteRecursively` consistently to clean up, sometimes in an `@After` method. _If anyone seconds the motion, I can create a more significant change that introduces a new test trait along the lines of `LocalSparkContext`, which provides management of temp directories for subclasses to take advantage of._ Author: Sean Owen <sowen@cloudera.com> Closes #732 from srowen/SPARK-1798 and squashes the following commits: 5af578e [Sean Owen] Try to consistently delete test temp dirs and files, and set deleteOnExit() for each b21b356 [Sean Owen] Remove work/ and checkpoint/ dirs with mvn clean bdd0f41 [Sean Owen] Remove duplicate module dir in log4j.properties output path for tests

* [SPARK-1592][streaming] Automatically remove streaming input blocksTathagata Das2014-04-243-14/+76
| | | | | | | | | | | | | | | The raw input data is stored as blocks in BlockManagers. Earlier they were cleared by cleaner ttl. Now since streaming does not require cleaner TTL to be set, the block would not get cleared. This increases up the Spark's memory usage, which is not even accounted and shown in the Spark storage UI. It may cause the data blocks to spill over to disk, which eventually slows down the receiving of data (persisting to memory become bottlenecked by writing to disk). The solution in this PR is to automatically remove those blocks. The mechanism to keep track of which BlockRDDs (which has presents the raw data blocks as a RDD) can be safely cleared already exists. Just use it to explicitly remove blocks from BlockRDDs.

* [SPARK-1332] Improve Spark Streaming's Network Receiver and InputDStream API ↵Tathagata Das2014-04-215-44/+359
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [WIP] The current Network Receiver API makes it slightly complicated to right a new receiver as one needs to create an instance of BlockGenerator as shown in SocketReceiver https://github.com/apache/spark/blob/master/streaming/src/main/scala/org/apache/spark/streaming/dstream/SocketInputDStream.scala#L51 Exposing the BlockGenerator interface has made it harder to improve the receiving process. The API of NetworkReceiver (which was not a very stable API anyways) needs to be change if we are to ensure future stability. Additionally, the functions like streamingContext.socketStream that create input streams, return DStream objects. That makes it hard to expose functionality (say, rate limits) unique to input dstreams. They should return InputDStream or NetworkInputDStream. This is still not yet implemented.

* SPARK-1488. Resolve scalac feature warnings during buildSean Owen2014-04-142-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For your consideration: scalac currently notes a number of feature warnings during compilation: ``` [warn] there were 65 feature warning(s); re-run with -feature for details ``` Warnings are like: ``` [warn] /Users/srowen/Documents/spark/core/src/main/scala/org/apache/spark/SparkContext.scala:1261: implicit conversion method rddToPairRDDFunctions should be enabled [warn] by making the implicit value scala.language.implicitConversions visible. [warn] This can be achieved by adding the import clause 'import scala.language.implicitConversions' [warn] or by setting the compiler option -language:implicitConversions. [warn] See the Scala docs for value scala.language.implicitConversions for a discussion [warn] why the feature should be explicitly enabled. [warn] implicit def rddToPairRDDFunctions[K: ClassTag, V: ClassTag](rdd: RDD[(K, V)]) = [warn] ^ ``` scalac is suggesting that it's just best practice to explicitly enable certain language features by importing them where used. This PR simply adds the imports it suggests (and squashes one other Java warning along the way). This leaves just deprecation warnings in the build.

* [SPARK-1386] Web UI for Spark StreamingTathagata Das2014-04-113-4/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When debugging Spark Streaming applications it is necessary to monitor certain metrics that are not shown in the Spark application UI. For example, what is average processing time of batches? What is the scheduling delay? Is the system able to process as fast as it is receiving data? How many records I am receiving through my receivers? While the StreamingListener interface introduced in the 0.9 provided some of this information, it could only be accessed programmatically. A UI that shows information specific to the streaming applications is necessary for easier debugging. This PR introduces such a UI. It shows various statistics related to the streaming application. Here is a screenshot of the UI running on my local machine. http://i.imgur.com/1ooDGhm.png This UI is integrated into the Spark UI running at 4040.

This PR provides the fix. Now, when the StreamingContext.stop() is called, the following sequence of steps will happen. 1. The driver will send a stop signal to all the active receivers. 2. Each receiver, when it gets a stop signal from the driver, first stop receiving more data, then waits for the thread that persists data blocks to BlockManager to finish persisting all receive data, and finally quits. 3. After all the receivers have stopped, the driver will wait for the Job Generator and Job Scheduler to finish processing all the received data. It also fixes the semantics of StreamingContext.start and stop. It will throw appropriate errors and warnings if stop() is called before start(), stop() is called twice, etc. Author: Tathagata Das <tathagata.das1565@gmail.com> Closes #247 from tdas/graceful-shutdown and squashes the following commits: 61c0016 [Tathagata Das] Updated MIMA binary check excludes. ae1d39b [Tathagata Das] Merge remote-tracking branch 'apache-github/master' into graceful-shutdown 6b59cfc [Tathagata Das] Minor changes based on Andrew's comment on PR. d0b8d65 [Tathagata Das] Reduced time taken by graceful shutdown unit test. f55bc67 [Tathagata Das] Fix scalastyle c69b3a7 [Tathagata Das] Updates based on Patrick's comments. c43b8ae [Tathagata Das] Added graceful shutdown to Spark Streaming.

| | | | | | | | | | | | | | (This follows from a side point on SPARK-1133, in discussion of the PR: https://github.com/apache/spark/pull/164 ) Commons IO is barely used in the project, and can easily be replaced with equivalent calls to Guava or the existing Spark `Utils.scala` class. Removing a dependency feels good, and this one in particular can get a little problematic since Hadoop uses it too.

|\ | | | | | | | | | | | | | | Moved DStream and PairDSream to org.apache.spark.streaming.dstream Similar to the package location of `org.apache.spark.rdd.RDD`, `DStream` has been moved from `org.apache.spark.streaming.DStream` to `org.apache.spark.streaming.dstream.DStream`. I know that the package name is a little long, but I think its better to keep it consistent with Spark's structure. Also fixed persistence of windowed DStream. The RDDs generated generated by windowed DStream are essentially unions of underlying RDDs, and persistent these union RDDs would store numerous copies of the underlying data. Instead setting the persistence level on the windowed DStream is made to set the persistence level of the underlying DStream.

|\ \ \ \ | | |_|/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Better error handling in Spark Streaming and more API cleanup Earlier errors in jobs generated by Spark Streaming (or in the generation of jobs) could not be caught from the main driver thread (i.e. the thread that called StreamingContext.start()) as it would be thrown in different threads. With this change, after `ssc.start`, one can call `ssc.awaitTermination()` which will be block until the ssc is closed, or there is an exception. This makes it easier to debug. This change also adds ssc.stop(<stop-spark-context>) where you can stop StreamingContext without stopping the SparkContext. Also fixes the bug that came up with PRs #393 and #381. MetadataCleaner default value has been changed from 3500 to -1 for normal SparkContext and 3600 when creating a StreamingContext. Also, updated StreamingListenerBus with changes similar to SparkListenerBus in #392. And changed a lot of protected[streaming] to private[streaming].
