Sergey Shelukhin updated HIVE-13596:
------------------------------------
Summary: HS2 should refresh UDFs more frequently, at least in multi-HS2
case (was: HS2 should refresh UDFs for each session, at least in multi-HS2
case)

> URL: https://issues.apache.org/jira/browse/HIVE-13596
> Project: Hive
> Issue Type: Bug
> Reporter: Sergey Shelukhin
>
> 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 could change the code to refresh the udf by name if it's missing, similar
> to getting a table or whatever; or we could refresh UDFs when a session is
> started in multi-HS2 case, or at some other convenient point.
