Examples of ZooKeeperWatcher

com.alibaba.wasp.zookeeper.ZooKeeperWatcher
Acts as the single ZooKeeper Watcher. One instance of this is instantiated for each Master, FServer, and client process.
This is the only class that implements {@link org.apache.zookeeper.Watcher}. Other internal classes which need to be notified of ZooKeeper events must register with the local instance of this watcher via {@link #registerListener}.
This class also holds and manages the connection to ZooKeeper. Code to deal with connection related events and exceptions are handled here.
