Chris Riccomini commented on SAMZA-393:
---------------------------------------
I am unable to reproduce this. I ran the test in a loop for hours and it never
showed up again.
I'm thinking that this could be an issue with bin/check-all.sh. It's possible
that some state is hanging around between test runs in check-all.sh, or that
there's some timing dependency that gets triggered when doing consecutive runs
in check-all.sh.
I've noticed that check-all.sh never completes successfully for me either. I
think samza-kafka:test doesn't have enough memory. Likely this happened after
the memory was dropped for Travis CI in SAMZA-386.
