Have Secure federated cluster with atleast two nameservices
Configure viewfs related configs
When we run the ls cmd in HDFS client ,we will call the method: org.apache.hadoop.fs.viewfs.ViewFileSystem.InternalDirOfViewFs#getFileStatus
it will try to get the group of the kerberos user. If the node has not this user, it fails.
Throws the following and exits.UserGroupInformation#getPrimaryGroupName
if (groups.isEmpty()) { throw new IOException("There is no primary group for UGI " + this); }
