org.apache.hadoop.hbase.master.TableStateManager

直接已知子类:

MirroringTableStateManager

@InterfaceAudience.Private
public class TableStateManager
extends Object

This is a helper class used to manage table states. This class uses hbase:meta as its store for table state so hbase:meta must be online before start() is called.
