Chao Sun updated HDFS-13749:
----------------------------
Description: In HDFS-12976 currently we discover NameNode state by calling
{{reportBadBlocks}} as a temporary solution. Here, we'll properly implement
this by using {{HAServiceProtocol#getServiceStatus}}. (was: 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.)
> Use getServiceStatus to discover observer namenodes
