Interface CoordinatedStateManager

All Known Implementing Classes:

BaseCoordinatedStateManager, ZkCoordinatedStateManager

@InterfaceAudience.Private
public interface CoordinatedStateManager

Implementations of this interface will keep and return to clients implementations of classes providing API to execute coordinated operations. This interface is client-side, so it does NOT include methods to retrieve the particular interface implementations. For each coarse-grained area of operations there will be a separate interface with implementation, providing API for relevant operations requiring coordination. Property hbase.coordinated.state.manager.class in hbase-site.xml controls which provider to use.
