org.apache.hadoop.hbase.coordination.BaseCoordinatedStateManager
Base class for {@link org.apache.hadoop.hbase.CoordinatedStateManager} implementations.Defines methods to retrieve coordination objects for relevant areas. CoordinatedStateManager reference returned from Server interface has to be casted to this type to access those methods.
