[jira] [Created] (HDFS-9389) Add maintenance states to AdminStates

Ming Ma created HDFS-9389:
-----------------------------

             Summary: Add maintenance states to AdminStates
                 Key: HDFS-9389
                 URL: https://issues.apache.org/jira/browse/HDFS-9389
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Ming Ma


This jira will add {{ENTERING_MAINTENANCE}} and {{IN_MAINTENANCE}} to {{AdminStates}} and protobuf. It will also provide the basic functionality to transition DN into or out of maintenance state from DN's state machine's point of view. The actual admins support and block management will be covered by separate jiras.
