> 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.
