org.apache.hadoop.hbase.zookeeper.ZKTable
Helper class for table state tracking for use by {@link AssignmentManager}. Reads, caches and sets state up in zookeeper. If multiple read/write clients, will make for confusion. Read-only clients other than AssignmentManager interested in learning table state can use the read-only utility methods {@link #isEnabledTable(ZooKeeperWatcher,String)}and {@link #isDisabledTable(ZooKeeperWatcher,String)}.
To save on trips to the zookeeper ensemble, internally we cache table state.
