Kevin Wilfong updated HIVE-2471:
--------------------------------
Description: Occasionally, when entries are added to the partition stats
table the program is halted before it can delete those entries, by an
exception, keyboard interrupt, etc. These build up to the point where the
table gets very large, and it hurts the performance of the update statement
which is often called. In order to fix this, I am adding a column to the table
which is auto-populated with the current timestamp. This will allow us to
create scripts that go through periodically and clean out old entries from the
table. (was: Occasionally, when entries are added to the partition stats table
