Stephan Ewen commented on FLINK-3744:
-------------------------------------
That probably has a root cause, like one of the taskmanagers not being able to
start properly (port conflict, or so)
Can you take a look at the logs for that test, see if you find something
interesting?
If it happened on Travis, [~uce] can give you a pointer how to enable log
upload from Travis to your S3 account, so you get full logs on failed builds.
