Examples of org.apache.hadoop.hbase.zookeeper.RootRegionTracker

org.apache.hadoop.hbase.zookeeper.RootRegionTracker
Tracks the root region server location node in zookeeper. Root region location is set by {@link RootLocationEditor} usually calledout of RegionServerServices. This class has a watcher on the root location and notices changes.
