Description

if we execute ls, it will throw following.

hdfs dfs -ls webhdfs://127.0.0.1:5978/
ls: Invalid value for webhdfs parameter "op"

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"”.
