Prasanth Jayachandran commented on HIVE-12005:
----------------------------------------------

LGTM, +1. Pending tests.

Are we getting rid of JDBC as well? JDBC is giving more trouble related to maxKeyPrefix across
different DBs. We are patching it here and there to work around the limits imposed by different
DBs.

> Currently, hbase is one of the mechanism to collect and store statistics. I have never
come across anyone using it. FileSystem based collection mechanism is default for few releases
and is working well. We shall remove hbase stats collector.
