Sean Owen commented on SPARK-7941:
----------------------------------

Which cache files are you referring to (what location?). YARN containers are 
cleaned up by YARN.

> 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
>
> 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.
