Review request for hive, Ashutosh Chauhan and Chao Sun.


Bugs: HIVE-9025
    https://issues.apache.org/jira/browse/HIVE-9025


Repository: hive


Description
-------

HIVE-5771 introduced a bug that when all partition columns are constants, the partition is
transformed to be a random  dispatch, which is not expected.

This patch adds a constant column in the above case to avoid random partitioning.
