Subject [jira] [Commented] (HIVE-13566) Auto-gather column stats - phase 1
Date Tue, 12 Dec 2017 09:27:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13566?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16287321#comment-16287321
] 

Lefty Leverenz commented on HIVE-13566:
---------------------------------------

Doc note:  This adds *hive.stats.column.autogather* and changes the description of *hive.stats.autogather*
in HiveConf.java for release 2.1.0, so the wiki needs to be updated.

* [Configuration Properties -- Statistics | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-Statistics]
** [Configuration Properties -- hive.stats.autogather | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.stats.autogather]
** [Configuration Properties -- hive.stats.column.autogather | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.stats.column.autogather]
(this link won't work until the documentation is done)

Added a TODOC2.1 label.

Update:  HIVE-13567 changes the default value of *hive.stats.column.autogather* to true in
release 3.0.0.
