> expunge command is supported for both encrypted and non-encrypted hdfs paths
> . This operation initially needs to discover/list all such paths.
> Listing/Discovering encrypted zone paths is only supported by superuser and
> expunge command misleads us by printing below message though its a warning .
> We could add some message in the expunge command description saying that the
> command supports encrypted zone paths only when run as superuser and it will
> continue listing and performing the operation for all non encrypted hdfs
> paths.
