Examples of org.apache.hadoop.hbase.MasterAddressTracker

org.apache.hadoop.hbase.MasterAddressTracker
Manages the location of the current active Master for this RegionServer.
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()}

    // Create the master address manager, register with zk, and start it.  Then
    // block until a master is available.  No point in starting up if no master
    // running.
    this.masterAddressManager = new MasterAddressTracker(this.zooKeeper, this);
    this.masterAddressManager.start();
    blockAndCheckIfStopped(this.masterAddressManager);


    // Wait on cluster being up.  Master will set this flag up in zookeeper
    // when ready.
