Lefty Leverenz commented on HIVE-12178:
---------------------------------------

Doc note:  This revises HIVE-12078's description for *hive.llap.io.lrfu.lambda*.  It needs
to be documented in the wiki for the 2.0.0 release.

* [Hive Configuration Properties (needs a new LLAP section) | https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties]
