[jira] [Created] (HDFS-2679) Add interface to query current state
to HAServiceProtocol
Add interface to query current state to HAServiceProtocol
----------------------------------------------------------
Key: HDFS-2679
URL: https://issues.apache.org/jira/browse/HDFS-2679
Project: Hadoop HDFS
Issue Type: Sub-task
Affects Versions: HA branch (HDFS-1623)
Reporter: Eli Collins
Assignee: Eli Collins
Let's add an interface to HAServiceProtocol to query the current state of a NameNode for use by the the CLI (HAAdmin) and Web UI (HDFS-2677). This essentially makes the names "active" and "standby" from ACTIVE_STATE and STANDBY_STATE public interfaces, which IMO seems reasonable. Unlike the other APIs we should be able to use the interface even when HA is not enabled (as by default a non-HA NN is active).
