----------------------------------

Hi, this issue is not quite resolved actually, please see the ticket [SPARK-12430|https://issues.apache.org/jira/browse/SPARK-12430] .
The clean-up does not delete blockmgr-<UUID> folder but only spark-<UUID> folder, even if now those directories are created under Mesos temporary path.

>             Project: Spark
>          Issue Type: Bug
>          Components: Mesos
>    Affects Versions: 1.5.1
>            Reporter: Iulian Dragos
>
> (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.
