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.
