> We are experiencing an issue with automatic /tmp folder deletion after framework completes.
Completing a M/R job using Spark 1.5.2 (same behavior as Spark 1.5.1) over Mesos will not
delete some temporary folders causing free disk space on server to exhaust. 
> Behavior of M/R job using Spark 1.4.1 over Mesos cluster:
> - Launched using spark-submit on one cluster node.
> - Following folders are created: */tmp/mesos/slaves/id#* , */tmp/spark-#/*  ,  */tmp/spark-#/blockmgr-#*
> - When task is completed */tmp/spark-#/* gets deleted along with */tmp/spark-#/blockmgr-#*
sub-folder.
> Behavior of M/R job using Spark 1.5.2 over Mesos cluster (same identical job):
> - Launched using spark-submit on one cluster node.
> - Following folders are created: */tmp/mesos/mesos/slaves/id** * , */tmp/spark-***/ *
 ,{color:red} /tmp/blockmgr-***{color}
> - When task is completed */tmp/spark-***/ * gets deleted but NOT shuffle container folder
{color:red} /tmp/blockmgr-***{color}
> Unfortunately, {color:red} /tmp/blockmgr-***{color} can account for several GB depending
on the job that ran. Over time this causes disk space to become full with consequences that
we all know. 
> Running a shell script would probably work but it is difficult to identify folders in
use by a running M/R or stale folders. I did notice similar issues opened by other users marked
as "resolved", but none seems to exactly match the above behavior. 
> I really hope someone has insights on how to fix it.
> Thank you very much!
