             Summary: 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.
