-----------------------------------
Hi [~yittg] thanks for your reporting.
Afaik the commit files action happens at the committer operator instead of the
JM size after the new sink api [1].
It means this would not happen if you use the new `FlinkSink`.[2]

> Key: FLINK-27377
> URL: https://issues.apache.org/jira/browse/FLINK-27377
> Project: Flink
> Issue Type: Bug
> Reporter: Yi Tang
> Priority: Major
>
> I have a case using FileSystem as batch sink, it will commit files by
> {{FinalizeOnMaster#finalizeGlobal}} while updating state from Running to
> Finished.
> When {{FinalizeOnMaster#finalizeGlobal}} method is blocked, the
> {{JobMaster#updateTaskExecutionState}} will also be blocked. Then the job
> manager can not respond any new requests until
> {{JobMaster#updateTaskExecutionState}} is complete.
