Kostas Kloudas commented on FLINK-15533:
----------------------------------------
I have [branch|https://github.com/kl0u/flink/tree/FLINK-15533] with a simple
fix but I will wait for travis before opening a PR. It does not change the
{{FileOutputFormat}}, as this change may be breaking for some users, but we can
do it in a follow-up issue.
I would appreciate also if [~lirui] could verify that the fix is actually
fixing the problem.
