Description

After STORM-2482, we can set cluster-wise principal and keytab (and configurations) instead of setting global principal and keytab for HDFS and HBase.
(Hive will be supported via STORM-2501.)

In AutoHDFS there's a missed spot which always uses global principal, and it throws some errors when global principal is not set.

It should prefer cluster-wise principal to global principal.
