Lefty Leverenz commented on HIVE-13596:
---------------------------------------
Doc note: This adds *hive.allow.udf.load.on.demand* to HiveConf.java so it
will need to be documented in the wiki for release 2.1.0.
* [Configuration Properties -- Query and DDL Execution |

> When multiple HS2s are run, creating a permanent fn is only executed on one
> of them, and the other HS2s don't get the new function. Unlike say with
> tables, where we always get stuff from db on demand, fns are registered at
> certain points in the code and if the new one is not registered, it will not
> be available.
> We should restore the pre-HIVE-2573 behavior of being able to refresh the
> UDFs on demand.
