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.
