Description

With the introduction of the Learner Master feature in ZOOKEEPER-3140, tracking the state of the Observers synced with the voting quorum became more difficult from an operational perspective. Observers could now be synced with any voting member and not just the leader and to discover where an observer was being hosted required digging in to the server logs or complex jmx queries.

 

Add commands that externalize the state of observers from the point of view of the voting quorum.
