We use ranger with kerberos. When enable ranger-kms for hdfs encryption, we got
an error from ranger admin web ui. On the premise that all configurations have
been completed, I can not list keys in ranger admin, errors are as follows:
Unauthenticated : Please check the permission in the policy for the user.

I studied the problem and found that this problem have nothing to do with
authentication, it is an exception caused by NPE. I try print that exception:
