[jira] [Commented] (SPARK-4514) ComplexFutureAction does not
preserve job group IDs
[ https://issues.apache.org/jira/browse/SPARK-4514?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14220359#comment-14220359 ]
Josh Rosen commented on SPARK-4514:
-----------------------------------
I plan to investigate / fix this soon, but I'm a bit swamped with other work; [~eje], any chance that you have spare cycles to hack on this?

> Key: SPARK-4514
> URL: https://issues.apache.org/jira/browse/SPARK-4514
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.1.0, 1.1.1, 1.2.0
> Reporter: Erik Erlandson
> Assignee: Josh Rosen
> Priority: Critical
>
> The current job group id of a Spark context is stored in the {{localProperties}} member value. This data structure is designed to be thread local, and its settings are not preserved when {{ComplexFutureAction}} instantiates a new {{Future}}.
> One consequence of this is that {{takeAsync()}} does not behave in the same way as other async actions, e.g. {{countAsync()}}. For example, this test (if copied into StatusTrackerSuite.scala), will fail, because {{"my-job-group2"}} is not propagated to the Future which actually instantiates the job:
> {code:java}
> test("getJobIdsForGroup() with takeAsync()") {
> sc = new SparkContext("local", "test", new SparkConf(false))
> sc.setJobGroup("my-job-group2", "description")
> sc.statusTracker.getJobIdsForGroup("my-job-group2") should be (Seq.empty)
> val firstJobFuture = sc.parallelize(1 to 1000, 1).takeAsync(1)
> val firstJobId = eventually(timeout(10 seconds)) {
> firstJobFuture.jobIds.head
> }
> eventually(timeout(10 seconds)) {
> sc.statusTracker.getJobIdsForGroup("my-job-group2") should be (Seq(firstJobId))
> }
> }
> {code}
> It also impacts current PR for SPARK-1021, which involves additional uses of {{ComplexFutureAction}}.
