use of org.apache.zookeeper.server.quorum.QuorumPeer in project zookeeper by apache.

the class ObserverLETest method testLEWithObserver.

     * of a leader by forming a 5-node, 2-observer ensemble (so quorum size is 2).
     * When all but the leader and one observer are shut down, the leader should
     * enter the 'looking' state, not stay in the 'leading' state.
