Lefty Leverenz commented on HIVE-12656:
---------------------------------------
Doc note: This changes the default value of *hive.compute.query.using.stats*
in release 2.2.0, so the wiki will need to be updated.
* [Configuration Properties -- hive.compute.query.using.stats |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.compute.query.using.stats]
For an example of how to document a changed default value, see:
* [Configuration Properties -- hive.metastore.execute.setugi |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.metastore.execute.setugi]
Added a TODOC2.2 label.
