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

Hi [~ashutoshc] , sorry as I was not following HIVE-13040 and I couldnt see any description in that JIRA, what is the use case that leads to generating job on split or 0 splits and/or 0-length files?  Is it empty buckets?  How were empty buckets handled before HIVE-13040?  Thanks.
