Lefty Leverenz commented on HIVE-8052:
--------------------------------------
Doc question: Does this need any user documentation besides the new
configuration parameter *hive.vectorized.execution.reduce.groupby.enabled*?
By the way, the latest HiveConf.java in trunk has six *hive.vectorized.xxx*
parameters that aren't documented in the wiki yet. So they all need to be
documented in a separate section of the "Configuration Properties" wikidoc.
