Review request for drill.

Bugs: DRILL-1742

Repository: drill-git


HiveScan.getSplits() already gets the table and partitions metadata using MetaStoreUtils.
We compute the total number of rows using the numRows property and store the computed number
of rows in rowCount attribute which is later returned by getScanStats().

created several partitioned and non-partitioned tables, loaded data in hive.

querying the tables I checked the logs to make sure the correct number of rows is computed.
