---------------------------------------------------------------

next time we have a maintenance, i will wipe /tmp completely so that we can at 
least try and see what's creating what...  right now it's such a mess that it's 
hard to attribute anything to anything.

i did watch as a spark build (spark-master-test-maven-hadoop-2.7, IIRC) dump a 
bunch of the liblz4-java3891256912513794605.so files in /tmp this morning on 
worker-08 (the number string changes for each file).

and, so far today, on just one worker, we've had 2628 of these files left in 
/tmp:

[root@amp-jenkins-worker-08 tmp]# ls -lt | grep liblz4 |grep "May 27" | wc -l
2628

i'm not worried about us running out of disk, and this is something i can 
manage on the system-level, but it'd still be nice to have well behaved tests.  
:)

> 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.
