Review request for drill, Aman Sinha and Jason Altekruse.
Bugs: DRILL-2408
https://issues.apache.org/jira/browse/DRILL-2408
Repository: drill-git
Description
-------
I updated ParquetRecordWriter to delete the last file created if it's empty (no
records written to it). I also added two unit tests one that checks the default
case where we try to create a table using a query that returns 0 rows, the
second case can happen if the ParquetRecordWriter flushes it's content just
after writing the last record, it will then create a new empty file.
