Rui Fan commented on FLINK-31036:
---------------------------------
I see that StateCheckpointedITCase fails when this commit[1] is merged.
I have an idea: Based on this commit, use a script to run
StateCheckpointedITCase(with LOG enabled) repeatedly to see if it can be
reproduced. I'll update here when I come to any conclusions.
