* [SPARK-9504] [STREAMING] [TESTS] Use eventually to fix the flaky testzsxwing2015-07-311-5/+5
| | | | | | | | | | | | | The previous code uses `ssc.awaitTerminationOrTimeout(500)`. Since nobody will stop it during `awaitTerminationOrTimeout`, it's just like `sleep(500)`. In a super overloaded Jenkins worker, the receiver may be not able to start in 500 milliseconds. Verified this in the log of https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/39149/ There is no log about starting the receiver before this failure. That's why `assert(runningCount > 0)` failed. This PR replaces `awaitTerminationOrTimeout` with `eventually` which should be more reliable.

| | | | | | | | | | | | | | | | | | | build and other potential test failures in Streaming See https://issues.apache.org/jira/browse/SPARK-9479 for the failure cause. The PR includes the following changes: 1. Make ReceiverTrackerSuite create StreamingContext in the test body. 2. Fix places that don't stop StreamingContext. I verified no SparkContext was stopped in the shutdown hook locally after this fix. 3. Fix an issue that `ReceiverTracker.endpoint` may be null. 4.

Thus number of records in block won't be counted if Block failed to unroll in memory. Which is fine. For MEMORY_DISK settings , if BlockManager not able to unroll block to memory, block will still get deseralized to Disk. Same for WAL based store. So for those cases ( storage level = memory + disk ) number of records will be counted even though the block not able to unroll to memory. thus I added the isFullyConsumed in the CountingIterator but have not used it as such case will never happen that block not fully consumed and ReceivedBlockHandler still get the block ID. I have added few test cases to cover those block unrolling scenarios also.

One thing to note here is that we already do some kind of scoping thing for call sites, so this patch adds the new RDD operation scoping logic in the same place. Also, this patch adds a `try finally` block to set the relevant variables in a safer way. tdas zsxwing ------------------------ **Before** <img src="https://cloud.githubusercontent.com/assets/2133137/7625996/d88211b8-f9b4-11e4-90b9-e11baa52d6d7.png" width="450px"/> -------------------------- **After** <img src="https://cloud.githubusercontent.com/assets/2133137/7625997/e0878f8c-f9b4-11e4-8df3-7dd611b13c87.png" width="650px"/> Author: Andrew Or <andrew@databricks.com> Closes #6034 from andrewor14/dag-viz-streaming and squashes the following commits: 932a64a [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming e685df9 [Andrew Or] Rename createRDDWith 84d0656 [Andrew Or] Review feedback 697c086 [Andrew Or] Fix tests 53b9936 [Andrew Or] Set scopes for foreachRDD properly 1881802 [Andrew Or] Refactor DStream scope names again af4ba8d [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming fd07d22 [Andrew Or] Make MQTT lower case f6de871 [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming 0ca1801 [Andrew Or] Remove a few unnecessary withScopes on aliases fa4e5fb [Andrew Or] Pass in input stream name rather than defining it from within 1af0b0e [Andrew Or] Fix style 074c00b [Andrew Or] Review comments d25a324 [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming e4a93ac [Andrew Or] Fix tests? 25416dc [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming 9113183 [Andrew Or] Add tests for DStream scopes b3806ab [Andrew Or] Fix test bb80bbb [Andrew Or] Fix MIMA? 5c30360 [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming 5703939 [Andrew Or] Rename operations that create InputDStreams 7c4513d [Andrew Or] Group RDDs by DStream operations and batches bf0ab6e [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming 05c2676 [Andrew Or] Wrap many more methods in withScope c121047 [Andrew Or] Merge branch 'master' of github.com:apache/spark into dag-viz-streaming 65ef3e9 [Andrew Or] Fix NPE a0d3263 [Andrew Or] Scope streaming operations instead of RDD operations

| | | | | | | | | | | | | | | scala.concurrent.ExecutionContext.Implicits.global" Learnt a lesson from SPARK-7655: Spark should avoid to use `scala.concurrent.ExecutionContext.Implicits.global` because the user may submit blocking actions to `scala.concurrent.ExecutionContext.Implicits.global` and exhaust all threads in it. This could crash Spark. So Spark should always use its own thread pools for safety. This PR removes all usages of `scala.concurrent.ExecutionContext.Implicits.global` and uses proper thread pools to replace them.
