--------------------------------------
Summary: Add admin command to display leader
Key: ZOOKEEPER-3385
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3385
Project: ZooKeeper
Issue Type: Improvement
Components: server
Affects Versions: 3.6.0
Reporter: Brian Nixon
Each QuorumPeer prints the identity of the server it believes is the leader in
its logs but that is not easily turned into diagnostic information about the
state of the ensemble. It can be useful in debugging various issues, both when
a quorum is struggling to be established and when a minority of peers are
failing to follow, to see at a glance which peers are following the leader
elected by the majority and which peers are either not following or following a
different server.
Create an admin command that exposes which server a peer believes is the
current leader.
