Review request for hive and Ashutosh Chauhan.
Bugs: HIVE-14204
https://issues.apache.org/jira/browse/HIVE-14204
Repository: hive-git
Description
-------
Lots of time is spent in sequential fashion to load dynamic partitioned dataset
in driver side.
E.g simple dynamic partitioned load as follows takes 300+ seconds
INSERT INTO web_sales_test partition(ws_sold_date_sk) select * from
tpcds_bin_partitioned_orc_200.web_sales;
Time taken to load dynamic partitions: 309.22 seconds
