Lefty Leverenz commented on HIVE-13343:
---------------------------------------

Doc note:  This adds *hive.llap.enable.grace.join.in.llap* to HiveConf.java so 
it will need to be documented in the LLAP section of Configuration Properties 
for release 2.1.0.

* [Configuration Properties -- LLAP | 
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-LLAP]

A release note would be helpful too, and Fix Version needs to be set.

Should usage notes be documented in the LLAP wikidoc?

> Due to performance reasons, we should disable use of hybrid grace hash join 
> in llap when dynamic partition hash join is not used. With dynamic partition 
> hash join, we need hybrid grace hash join due to the possibility of skews.
