> 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.
