I am closing this based on the lack of relevant logging, Tim's observation and
the rarity of this symptom.

> I can't figure out which test may have caused it, other than it's a custom
> cluster test. The minidump path is the clue there.
> https://jenkins.impala.io/job/ubuntu-16.04-from-scratch/3346/artifact/Impala/logs_static/logs/custom_cluster_tests/minidumps/impalad/
> All the tests passed. The timestamp of the minidump was not preserved across
> the archive, so I can't backtrack the timestamp of the file to the timestamps
> of the tests running at the time. I've combed through custom cluster log
> sections and can't find anything, either.
