Subject [jira] [Comment Edited] (HIVE-16423) Add hint to enforce semi join optimization
Date Sun, 14 May 2017 05:41:04 GMT

----------------------------------------------------------------

Doc note:  The hint and *hive.tez.dynamic.semijoin.reduction.hint.only* need to be documented
in the wiki.

* [Hive on Tez | https://cwiki.apache.org/confluence/display/Hive/Hive+on+Tez]
* [Join Optimization | https://cwiki.apache.org/confluence/display/Hive/LanguageManual+JoinOptimization]
* [Configuration Properties -- Tez | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-Tez]

Added a TODOC3.0 label.

Edit (14/May/17):  HIVE-16610 removes *hive.tez.dynamic.semijoin.reduction.hint.only* before
the 3.0.0 release, so that doesn't need to be documented.  But the hint should still be documented,
and a release note would be helpful.
