Tzu-Li (Gordon) Tai commented on FLINK-10895:
---------------------------------------------
I've been running this test in a loop for 50 times, and all attempts succeeded
without errors.
Also, this hasn't popped up in quite a while.
It could have been some instability with the mini clusters before, causing jobs
to fail (this ITCase submits an actual Flink job.)
So, I'm going to close this for now. Please reopen if this somehow pops up
again.
