* Improvements to external sortingPatrick Wendell2014-01-134-12/+52
| | | | | | | 1. Adds the option of compressing outputs. 2. Adds batching to the serialization to prevent OOM on the read side. 3. Slight renaming of config options. 4. Use Spark's buffer size for reads in addition to writes.

|\ | | | | | | | | | | Remove now un-needed hostPort option I noticed this was logging some scary error messages in various places. After I looked into it, this is no longer really used. I removed the option and re-wrote the one remaining use case (it was unnecessary there anyways).

|\ \ | | | | | | | | | | | | | | | Disable shuffle file consolidation by default After running various performance tests for the 0.9 release, this still seems to have performance issues even on XFS. So let's keep this off-by-default for 0.9 and users can experiment with it depending on their disk configurations.

|\ \ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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].

|\ \ \ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting load defaults to true in executor This preserves the behavior in earlier releases. If properties are set for the executors via `spark-env.sh` on the slaves, then they should take precedence over spark defaults. This is useful for if system administrators are setting properties for a standalone cluster, such as shuffle locations. /cc @andrewor14 who initially reported this issue.

|\ \ \ \ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert PR 381 This PR missed a bunch of test cases that require "spark.cleaner.ttl". I think it is what is causing test failures on Jenkins right now (though it's a bit hard to tell because the DNS for cs.berkeley.edu is down). I'm submitting this to see if it fixes jeknins. I did try just patching various tests but it was taking a really long time because there are a bunch of them, so for now I'm just seeing if a revert works.

|\ \ \ \ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We clone hadoop key and values by default and reuse objects if asked to. We try to clone for most common types of writables and we call WritableUtils.clone otherwise intention is to optimize, for example for NullWritable there is no need and for Long, int and String creating a new object with value set would be faster than doing copy on object hopefully. There is another way to do this PR where we ask for both key and values whether to clone them or not, but could not think of a use case for it except either of them is actually a NullWritable for which I have already worked around. So thought that would be unnecessary.

A convenience method is provided to generate a random client id that should satisfy this criteria - generateClientId(). Returns a randomly generated client identifier based on the current user's login name and the system time. As the client identifier is used by the server to identify a client when it reconnects, the client must use the same identifier between connections if durable subscriptions are to be used.
