Dong Lin commented on FLINK-20928:
----------------------------------
According to the test history of the testCommitOffsetsWithoutAliveFetchers [1],
the timeout failure happened only once from 1/26 - 2/26. According to the test
history of testOffsetCommitOnCheckpointComplete [2], this test has not failed
since 1/11. And I am not able to reproduce failure of either test in the Flink
master branch (githash 3ac83641c52dfa4fa67366c62335bcb7ee8a6624).
So the impact of this failure is low and it is very hard to figure out why it
previously failed. It seems reasonable to just close this JIRA because the bug
is not reproducible.
