Review request for hive and Ashutosh Chauhan.


1. Changed not to reset stats when "compute statistics noscan" is used
2. Removed assert in Utilities.getHashedStatsPrefix() which is added in previous diff. That
makes some tests fail (stats19.q, etc.)

Bugs: HIVE-5936

Repository: hive-git


With counter mechanism, MR job is successful, but StatsTask on client fails with NPE

Diffs (updated)
