Since 2.0.0. To be removed in 3.0.0.

@Deprecated
 @InterfaceAudience.Private
public class MirroringTableStateManager
extends TableStateManager

A subclass of TableStateManager that mirrors change in state out to zookeeper for hbase-1.x clients to pick up; hbase-1.x clients read table state of zookeeper rather than from hbase:meta as hbase-2.x clients do. Set "hbase.mirror.table.state.to.zookeeper" to false to disable mirroring. See in HMaster where we make the choice. The below does zk updates on a best-effort basis only. If we fail updating zk we keep going because only hbase1 clients suffer; we'll just log at WARN level.
