-------------------------------------
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.
