Sean Owen commented on SPARK-15619:
-----------------------------------
Interesting, looks like it's related to the lz4 library, and I see a similar
issue reported for Cassandra:
https://issues.apache.org/jira/browse/CASSANDRA-7712
It does create this temp library:
https://github.com/jpountz/lz4-java/blob/b69d5676f74344bf04068594644fa5ecc2bb6a67/src/java/net/jpountz/util/Native.java#L81
but seems to do a pretty comprehensive job of trying to clean it up at shutdown.
It might be left around after hard JVM failures / exits, in which case it may
unfortunately be a side effect of testing failure conditions. I don't see
anything in Spark that tries to manage it, and not sure it could.

> Reporter: shane knapp

> spark builds aren't cleaning up /tmp after they run... it's hard to pinpoint
> EXACTLY what is left there by the spark builds (as other builds are also
> guilty of doing this), but a quick perusal of the /tmp directory during some
> spark builds show that there are myriad empty directories being created and a
> massive pile of shared object libraries being dumped there.
> $ for x in $(cat jenkins_workers.txt ); do echo $x; ssh $x "ls -l /tmp/*.so |
> wc -l"; done
> amp-jenkins-worker-01
> 0
> ls: cannot access /tmp/*.so: No such file or directory

> to help combat this, i set up a cron job on each worker that runs tmpwatch
> during system downtime on sundays to clean up files older than a week.
