Examples of org.apache.hadoop.hbase.catalog.CatalogTracker

org.apache.hadoop.hbase.catalog.CatalogTracker
Tracks the availability of the catalog tables -ROOT- and .META.. This class is "read-only" in that the locations of the catalog tables cannot be explicitly set. Instead, ZooKeeper is used to learn of the availability and location of -ROOT-. -ROOT- is used to learn of the location of .META. If not available in -ROOT-, ZooKeeper is used to monitor for a new location of .META..
Call {@link #start()} to start up operation. Call {@link #stop()}} to interrupt waits and close up shop.
