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

Siying, the new patch looks good in general, but can you open a different JIRA and upload your patch to that?

> If there are too many files need to be closed in FileSinkOperator (e.g., if DynamicPartition/FileSpray is turned on), there could be many files generated by each task and they need to be closed at the FileSinkOperator.closeOp(). If the NN is overloaded each file close could take more than 1 sec. This sometimes make JT think the task is dead since it takes too long to close all the files and without any progress report. We need to report progress after a while during file closing.
