A note for the community - the /tmp file problem **did** reoccur for us. As
it turns out, the timeout default for starting up topologies in Monit was set
too low. Normally, Storm cleans up after itself whether a topology succeeds or
fails. But due to Monit's timeout setting, it was killing the process prior to
completion. As a result, the tmp jar files were being left in /tmp, and Monit
continued to retry every minute or two, subsequently filling up the disk space
pretty quickly with the ~70MB uber jars.
