Rajat Khandelwal updated HIVE-13903:
------------------------------------
Description: 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.
> getFunctionInfo is downloading jar on every call
