[jira] [Created] (HDFS-13749) Implement a new client protocol method to get NameNode state

Chao Sun created HDFS-13749:
-------------------------------

             Summary: Implement a new client protocol method to get NameNode state
                 Key: HDFS-13749
                 URL: https://issues.apache.org/jira/browse/HDFS-13749
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Chao Sun
            Assignee: Chao Sun


Currently {{HAServiceProtocol#getServiceStatus}} requires super user privilege. Therefore, as a temporary solution, in HDFS-12976 we discover NameNode state by calling {{reportBadBlocks}}. Here, we'll properly implement this by adding a new method in client protocol to get the NameNode state.
