Amareshwari Sriramadasu commented on HIVE-13903:
------------------------------------------------
[~sershe], HIVE-6672 (which is marked in the code comment) was adding jars
under a check, but later changes has removed the check. so, putting it back
looks fine to me.
If no objections, would like to commit this. Thanks
> getFunctionInfo is downloading jar on every call

>
> on queries using permanent udfs, the jar file of the udf is downloaded
> multiple times. Each call originating from Registry.getFunctionInfo. This
> increases time for the query, especially if that query is just an explain
> query. The jar should be downloaded once, and not downloaded again if the udf
> class is accessible in the current thread.
