Lefty Leverenz commented on HIVE-17475:
---------------------------------------
Doc note: The hint "+ mapjoin(None)" should be documented in the wiki, with
version information.
I suggest documenting it in three places:
* [Configuration Properties -- hive.auto.convert.join |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.auto.convert.join]
* [Joins -- MapJoin Restrictions |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Joins#LanguageManualJoins-MapJoinRestrictions]
* [Join Optimization -- Optimize Auto Join Conversion |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+JoinOptimization#LanguageManualJoinOptimization-OptimizeAutoJoinConversion]
(or add a new subsection after this one)
Added a TODOC3.0 label.
