Subject [jira] [Commented] (HIVE-12053) Stats performance regression caused by HIVE-11786
Date Wed, 14 Oct 2015 20:31:05 GMT

    [ https://issues.apache.org/jira/browse/HIVE-12053?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14957690#comment-14957690

Siddharth Seth commented on HIVE-12053:
---------------------------------------

[~ctang.ma] - the patch looks good to me. It's a direct revert of HIVE-11786. Does another
jira need to be created to capture the intent of HIVE-11786, without the normalization ?

> HIVE-11786 tried to normalize table TAB_COL_STATS/PART_COL_STATS but caused performance
regression.
