-----------------------------------

Hi, [~yittg]

Thanks for your detail explanation. 

Do you have already some investigation about why the `finalizeGlobal` block?  And would you like to share the sql about how you use/configure the Table File sink. AFAIK the table file sink only write a _SUCCESS file, which should not block very long time.  If we could find the root cause of the block and resolve it I think it might be the most easy way.

> 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.
