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.

* [Configuration Properties |

> Vectorization: min() on TimeStamp datatype fails with error "Vector aggregate
