Looks like the rename operation has been improved in HADOOP-15323.
And it has been adopted in newer flink versions, so this issue will be not obvious in the example i provided.

I'll also try to upgrade the hadoop-aliyun used by my flink to check if there is a significant improvement.

> 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 master can not respond any new requests until {{JobMaster#updateTaskExecutionState}} is complete.
