Yun Tang commented on FLINK-18637:
----------------------------------
[~oripwk] What's the max parallelism of your job? If your job does not assign
explicit max parallelism, what's your largest parallelism in your job?
If we really has the key group 13880 and did not set the max parallelism
explicitly. The operator parallelism of the keyed operator should be at least
5462. Is that true for your job?
I ask this to figure out whether the key group 13880 could existed.
BTW, have you ever watched this behavior before or can you reproduce this with
some simple job with fake data?
