---------------------------------------
No, it's not a duplicate, but fixed by the same PR :)
> Shuffle files left behind on Mesos without dynamic allocation
> -------------------------------------------------------------
>
> Key: SPARK-10975
> URL: https://issues.apache.org/jira/browse/SPARK-10975
> Project: Spark
> Issue Type: Bug
> Components: Mesos
> Affects Versions: 1.5.1
> Reporter: Iulian Dragos
> Priority: Blocker
>
> (from mailing list)
> Running on Mesos in coarse-grained mode. No dynamic allocation or shuffle
> service.
> I see that there are two types of temporary files under /tmp folder
> associated with every executor: /tmp/spark-<UUID> and /tmp/blockmgr-<UUID>.
> When job is finished /tmp/spark-<UUID> is gone, but blockmgr directory is
> left with all gigabytes in it.
> The reason is that logic to clean up files is only enabled when the shuffle
> service is running, see https://github.com/apache/spark/pull/7820
> The shuffle files should be placed in the Mesos sandbox or under `tmp/spark`
> unless the shuffle service is enabled.
