Subject [Impala-CR](cdh5-trunk) IMPALA-2653: COUNT DISTINCT performance is not monotonic.
Date Mon, 07 Mar 2016 21:45:15 GMT
Jim Apple has abandoned this change.

Change subject: IMPALA-2653: COUNT DISTINCT performance is not monotonic.
......................................................................


Abandoned
