* SPARK-2932 [STREAMING] Move MasterFailureTest out of "main" source directorySean Owen2014-09-252-36/+8
| | | | | | | | | | | | (HT @vanzin) Whatever the reason was for having this test class in `main`, if there is one, appear to be moot. This may have been a result of earlier streaming test reorganization. This simply puts `MasterFailureTest` back under `test/`, removes some redundant copied code, and touches up a few tiny inspection warnings along the way. Author: Sean Owen <sowen@cloudera.com> Closes #2399 from srowen/SPARK-2932 and squashes the following commits: 3909411 [Sean Owen] Move MasterFailureTest to src/test, and remove redundant TestOutputStream

* [Spark-3490] Disable SparkUI for testsAndrew Or2014-09-114-13/+41
| | | | | | | | | | | | | | | | We currently open many ephemeral ports during the tests, and as a result we occasionally can't bind to new ones. This has caused the `DriverSuite` and the `SparkSubmitSuite` to fail intermittently. By disabling the `SparkUI` when it's not needed, we already cut down on the number of ports opened significantly, on the order of the number of `SparkContexts` ever created. We must keep it enabled for a few tests for the UI itself, however.

* [SPARK-2886] Use more specific actor system name than "spark"Andrew Or2014-08-251-5/+5
| | | | | | | | | | | | | | | | | | | | | | | As of #1777 we log the name of the actor system when it binds to a port. The current name "spark" is super general and does not convey any meaning. For instance, the following line is taken from my driver log after setting `spark.driver.port` to 5001. ``` 14/08/13 19:33:29 INFO Remoting: Remoting started; listening on addresses: [akka.tcp://sparkandrews-mbp:5001] 14/08/13 19:33:29 INFO Remoting: Remoting now listens on addresses: [akka.tcp://sparkandrews-mbp:5001] 14/08/06 13:40:05 INFO Utils: Successfully started service 'spark' on port 5001. ``` This commit renames this to "sparkDriver" and "sparkExecutor".

* [SPARK-2454] Do not ship spark home to WorkersAndrew Or2014-08-021-1/+0
| | | | | | | | | | | | | | | | | When standalone Workers launch executors, they inherit the Spark home set by the driver. This means if the worker machines do not share the same directory structure as the driver node, the Workers will attempt to run scripts (e.g. bin/compute-classpath.sh) that do not exist locally and fail. This is a common scenario if the driver is launched from outside of the cluster. The solution is to simply not pass the driver's Spark home to the Workers. This PR further makes an attempt to avoid overloading the usages of `spark.home`, which is now only used for setting executor Spark home on Mesos and in python. This is based on top of #1392 and originally reported by YanTangZhai. Tested on standalone cluster.

This is a common cause for OOMs especially when (1) the BlockManager has little free space left in memory, and (2) the partition is large. **Solution.** We maintain a global memory pool of `M` bytes shared across all threads, similar to the way we currently manage memory for shuffle aggregation. Then, while we unroll each partition, periodically check if there is enough space to continue. If not, drop enough RDD blocks to ensure we have at least `M` bytes to work with, then try again. If we still don't have enough space to unroll the partition, give up and drop the block to disk directly if applicable. **New configurations.** - `spark.storage.bufferFraction` - the value of `M` as a fraction of the storage memory. (default: 0.2) - `spark.storage.safetyFraction` - a margin of safety in case size estimation is slightly off. This is the equivalent of the existing `spark.shuffle.safetyFraction`. (default 0.9) For more detail, see the [design document](https://issues.apache.org/jira/secure/attachment/12651793/spark-1777-design-doc.pdf). Tests pending for performance and memory usage patterns.

* SPARK-2657 Use more compact data structures than ArrayBuffer in groupBy & ↵Matei Zaharia2014-07-251-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | cogroup JIRA: https://issues.apache.org/jira/browse/SPARK-2657 Our current code uses ArrayBuffers for each group of values in groupBy, as well as for the key's elements in CoGroupedRDD. ArrayBuffers have a lot of overhead if there are few values in them, which is likely to happen in cases such as join. In particular, they have a pointer to an Object[] of size 16 by default, which is 24 bytes for the array header + 128 for the pointers in there, plus at least 32 for the ArrayBuffer data structure. This patch replaces the per-group buffers with a CompactBuffer class that can store up to 2 elements more efficiently (in fields of itself) and acts like an ArrayBuffer beyond that. For a key's elements in CoGroupedRDD, we use an Array of CompactBuffers instead of an ArrayBuffer of ArrayBuffers. There are some changes throughout the code to deal with CoGroupedRDD returning Array instead. We can also decide not to do that but CoGroupedRDD is a `DeveloperAPI` so I think it's okay to change it here.

* [STREAMING] SPARK-2009 Key not found exception when slow receiver startsVadim Chekan2014-06-171-1/+1
| | | | | | | | | | | | | | | | | | | | | I got "java.util.NoSuchElementException: key not found: 1401756085000 ms" exception when using kafka stream and 1 sec batchPeriod. Investigation showed that the reason is that ReceiverLauncher.startReceivers is asynchronous (started in a thread). https://github.com/vchekan/spark/blob/master/streaming/src/main/scala/org/apache/spark/streaming/scheduler/ReceiverTracker.scala#L206 In case of slow starting receiver, such as Kafka, it easily takes more than 2sec to start. In result, no single "compute" will be called on ReceiverInputDStream before first batch job is executed and receivedBlockInfo remains empty (obviously). Batch job will cause ReceiverInputDStream.getReceivedBlockInfo call and "key not found" exception. The patch makes getReceivedBlockInfo more robust by tolerating missing values.

* SPARK-1798. Tests should clean up temp filesSean Owen2014-05-125-2/+11
| | | | | | | | | | | | | | | | | | | | 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 Das2014-04-245-18/+90
| | | | | | | | | | | | | | | 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-1540] Add an optional Ordering parameter to PairRDDFunctions.Matei Zaharia2014-04-233-14/+19
| | | | | | | | | | | | | | | | | | | | In https://issues.apache.org/jira/browse/SPARK-1540 we'd like to look at Spark's API to see if we can take advantage of Comparable keys in more places, which will make external spilling more efficient. This PR is a first step towards that that shows how to pass an Ordering when available and still continue functioning otherwise. It does this using a new implicit parameter with a default value of null. The API is currently only in Scala -- in Java we'd have to add new versions of mapToPair and such that take a Comparator, or a new method to add a "type hint" to an RDD. We can address those later though. Unfortunately requiring all keys to be Comparable would not work without requiring RDDs in general to contain only Comparable types. The reason is that methods such as distinct() and intersection() do a shuffle, but should be usable on RDDs of any type. So ordering will have to remain an optimization for the types that can be ordered. I think this isn't a horrible outcome though because one of the nice things about Spark's API is that it works on objects of *any* type, without requiring you to specify a schema or implement Writable or stuff like that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [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.
