> When hiveserver2 load udfs, Registry will use session specified classloader
> to load them and add cache the classloader. When user don't set the aux
> jars, the classloader cached is equal to the session's parent classloader,
> in our case, we don't set the aux jars while update the session's parent
> classloader periodicity to update user jars dynamically. It's should do a
> sanity check when Registry closes the cached classloaders.
