> 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.
