>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: webhdfs
>    Affects Versions: 3.1.2
>            Reporter: KWON BYUNGCHANG
>            Priority: Minor

> I have two secure hadoop cluster.  Both cluster use cross-realm authentication. 
> [user_a@A.COM|mailto:user_a@A.COM] can access to HDFS of B.COM realm
> by the way, hadoop username of user_a@A.COM  in B.COM realm is  cross_realm_a_com_user_a.
> hdfs dfs command of user_a@A.COM using B.COM webhdfs failed.
> root cause is  webhdfs that connect secure hdfs use user.name parameter.
> according to webhdfs spec,  insecure webhdfs use user.name,  secure webhdfs use SPNEGO
for authentication.
> I think webhdfs that connect secure hdfs  should not use user.name parameter.
> I will attach patch.
> below is error log
>  
> {noformat}
> $ hdfs dfs -ls  webhdfs://b.com:50070/
> ls: Usernames not matched: name=user_a != expected=cross_realm_a_com_user_a
>  
> # user.name in cross realm webhdfs
> $ curl -u : --negotiate 'http://b.com:50070/webhdfs/v1/?op=GETDELEGATIONTOKEN&user.name=user_a' 
> {"RemoteException":{"exception":"SecurityException","javaClassName":"java.lang.SecurityException","message":"Failed
to obtain user group information: java.io.IOException: Usernames not matched: name=user_a
