Wilfred Spiegelenburg commented on SPARK-7705:
----------------------------------------------
I think the limitation that we currently set in the ApplicationMaster.scala on
line
[#120|https://github.com/apache/spark/blob/master/yarn/src/main/scala/org/apache/spark/deploy/yarn/ApplicationMaster.scala#L120]
is far to limiting.
The {{cleanupStagingDir(fs)}} should be moved out of the {{if (!unregistered)}}.
I have not tested this yet but this seems to be far more logical. Since we're
in the shutdown hook it should also catch our case:
{code}
if (finalStatus == FinalApplicationStatus.SUCCEEDED || isLastAttempt)
{
// we only want to unregister if we don't want the RM to retry
if (!unregistered) {
unregister(finalStatus, finalMsg)
}
// Since we're done we should clean up the staging directory
cleanupStagingDir(fs)
}
{code}
Not sure how to create a PR to check and discuss this change
> Cleanup of .sparkStaging directory fails if application is killed
> -----------------------------------------------------------------
>
> Key: SPARK-7705
> URL: https://issues.apache.org/jira/browse/SPARK-7705
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Affects Versions: 1.3.0
> Reporter: Wilfred Spiegelenburg
> Priority: Minor
>
> When a streaming application is killed while running on YARN the
> .sparkStaging directory is not cleaned up. Setting
> spark.yarn.preserve.staging.files=false does not help and still leaves the
> files around.
> The changes in SPARK-7503 do not catch this case since there is no exception
> in the shutdown. When the application gets killed the AM gets told to
> shutdown and the shutdown hook is run but the clean up is not triggered.
