Iulian Dragos commented on SPARK-12430:
---------------------------------------
Are you using 1.6? In that case, the blockmgr directory should really be inside
your Mesos sandbox, not under {{/tmp}}. At least, that's what I see when I try
out.
Note that, in case the external shuffle service isn't running that directory
should be deleted *even under the Mesos sandbox*. In my tests I see that it's
not always deleted, so I think there's a race condition somewhere. There's a PR
that would probably fix that:

> Key: SPARK-12430
> URL: https://issues.apache.org/jira/browse/SPARK-12430
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.5.1, 1.5.2, 1.6.0
> Environment: Ubuntu server
> Reporter: Fede Bar
>
> 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!
