Brahma Reddy Battula commented on HDFS-12950:
---------------------------------------------

[~jojochuang] thanks for the patch. Apporach looks good to me.

I feel, additionally we can mention that  if we can pass "-Dhadoop.security.authentication=simple" ls
will work...?

> if we execute ls, it will throw following.
> {noformat}
> hdfs dfs -ls webhdfs://127.0.0.1:5978/
> ls: Invalid value for webhdfs parameter "op"
> {noformat}
> When client is configured with security (i.e "hadoop.security.authentication= KERBEROS)
, 
> then webhdfs will request getdelegation token which is not implemented and hence it will
 throw “ls: Invalid value for webhdfs parameter "op"”.
