Sean Owen commented on SPARK-7941:
----------------------------------
I see, scratch that. 'hadoop' is usually a user for MapReduce, but I'm used to
a 'spark' user for Spark jobs. EMR is different.
Try with the latest master. Several cleanup items have been improved since 1.3
but I don't know if they're relevant. Last time I looked all temp dirs appear
correctly deleted on shutdown.
> Cache Cleanup Failure when job is killed by Spark
> --------------------------------------------------
>
> Key: SPARK-7941
> URL: https://issues.apache.org/jira/browse/SPARK-7941
> Project: Spark
> Issue Type: Bug
> Components: PySpark, YARN
> Affects Versions: 1.3.1
> Reporter: Cory Nguyen
> Attachments: screenshot-1.png
>
>
> Problem/Bug:
> If a job is running and Spark kills the job intentionally, the cache files
> remains on the local/worker nodes and are not cleaned up properly. Over time
> the old cache builds up and causes "No Space Left on Device" error.
> The cache is cleaned up properly when the job succeeds. I have not verified
> if the cached remains when the user intentionally kills the job.
