-------------------------------
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.
