Sergey Shelukhin commented on HIVE-2573:
This patch breaks some scenarios for multi-HS2 deployments, due to the code
that talks to metastore being removed from getFunctionNames(). [~navis] is
there a reason why this code had to be removed? I filed HIVE-13596 before I
knew this patch existed (I was assuming the scenario in HIVE-13596 never
worked); restoring the metastore-calling code, possibly with a config flag,
could be one way to fix the issue described there. Ideally, the metastore call
should only happen if the UDF is not found locally; that can be the next step,
for now we can just fix the issue by restoring the old behavior.

> Currently the function registry is shared resource and could be overrided by
> other users when using HiveServer. If per-session function registry is
> provided, this situation could be prevented.
