    Description

      We worked hard towards faster update stats for columns of a partition of a table previously

      https://issues.apache.org/jira/browse/HIVE-7736

      and

      https://issues.apache.org/jira/browse/HIVE-7876

      Although there is some improvement, it is only correct in the first run. There will be duplicate column stats later. Thanks to Eugene Koifman 's comments
