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()}
