Subject [jira] [Created] (HDFS-9389) Add maintenance states to AdminStates
Date Fri, 06 Nov 2015 01:53:27 GMT
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.
