---------------------------------------
Summary: HS2 should refresh UDFs for each session, at least in
multi-HS2 case
Key: HIVE-13596
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 in other such logical point.
