multi-partition inserts
-----------------------
Key: HIVE-1002
URL: https://issues.apache.org/jira/browse/HIVE-1002
Project: Hadoop Hive
Issue Type: New Feature
Reporter: Zheng Shao
We should allow queries like this into a partitioned table:
{code}
CREATE TABLE (a STRING, b STRING, c STRING)
PARTITIONED BY (ds STRING, ts STRING);
INSERT OVERWRITE TABLE x PARTITION (ds = '2009-12-12')
SELECT a, b, c, ts FROM xxx;
{code}
Basically, allowing users to overwrite multiple partitions at a time.
The partition values specified in PARTITION part (if any) should be a prefix of
the partition keys.
The rest of the partition keys goes to the end of the SELECT expression list.
