Nicholas Chammas commented on SPARK-3431: ----------------------------------------- I think I'm on to something, but I need some help. I think I understand how to tell SBT to fork JVMs for tests, and I also think I got how to specify how the tests should be grouped in the various forked JVMs. It's not working because I think the forked JVMs are not getting passed all the options they need. Basically, I don't think that the reference to {{javaOptions}} [here in this line|https://github.com/nchammas/spark/blob/ab127b798dbfa9399833d546e627f9651b060918/project/SparkBuild.scala#L429] actually has all the options [defined earlier|https://github.com/nchammas/spark/blob/ab127b798dbfa9399833d546e627f9651b060918/project/SparkBuild.scala#L403-L418]. I don't know much Scala. If anyone could review what I have so far give me some pointers, that would be great! You can see all the variations I've tried along with the associated output in [the open pull request|https://github.com/apache/spark/pull/3564]. I know we want to get this working with Maven, but I figured getting it to work first with SBT wouldn't be a bad thing. > Parallelize execution of tests > ------------------------------ > > Key: SPARK-3431 > URL: https://issues.apache.org/jira/browse/SPARK-3431 > Project: Spark > Issue Type: Improvement > Components: Build > Reporter: Nicholas Chammas > > Running all the tests in {{dev/run-tests}} takes up to 2 hours. A common > strategy to cut test time down is to parallelize the execution of the tests. > Doing that may in turn require some prerequisite changes to be made to how > certain tests run. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
