Review request for hive, Ashutosh Chauhan and Owen O'Malley.
Bugs: HIVE-5325
https://issues.apache.org/jira/browse/HIVE-5325
Repository: hive-git
Description
-------
HIVE-5324 adds new interfaces that can be implemented by ORC reader/writer to
provide statistics. Writer provided statistics is used to update
table/partition level statistics in metastore. Reader provided statistics can
be used for reducer estimation, CBO etc. in the absence of metastore statistics.
