Ning Zhang commented on HIVE-1002:
----------------------------------
1) hive.merge.mapfiles/mapredfiles will be set to false internally if dynamic
partitioning is enabled. I have modified some of the tests to remove the
explicit setting of hive.merge.* to false. I'll file a followup JIRA to address
merging.
2) drop tables are added to the positive tests.
3) load_dyn_part14.q was added to positive tests for HIVE_DEFAULT_PARTITION. I
didn't figure out how to enter unicode in hive cli ('\u8888' seems not work.
I'll file a following up JiRA for this and another negative test case where
exception was thrown after job finished (TestNegativeCliDriver doesn't work for
this case either).
Will upload a new patch addressing the above comments.

> 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.
