serves the client's read requests.Figure 4:zookeeper Ensemble Architecture4 shows a typical zookeeper ensemble, a server as leader, and others as follower. When ensemble is started, leader is selected, and all follower replicate leader status. All write requests are routed through leader, and the changes are broadcast to all follower. Change broadcasts are called atomic broadcasts.Use of

Currently, the zookeeper operation is done serially in the controller.Under normal circumstances, when the agent is cleanly shut down, the controller will proactively turn the leader off and off th
