Examples of MasterAddressTracker

com.alibaba.wasp.zookeeper.MasterAddressTracker
Manages the location of the current active FMaster for the FServer.
Listens for ZooKeeper events related to the master address. The node /master will contain the address of the current master. This listener is interested in NodeDeleted and NodeCreated events on /master.
Utilizes {@link ZooKeeperNodeTracker} for zk interactions.
You can get the current master via {@link #getMasterAddress()} or via{@link #getMasterAddress(ZooKeeperWatcher)} if you do not have a runninginstance of this Tracker in your context.
This class also includes utility for interacting with the master znode, for writing and reading the znode content.
