Class VisibilityReplication

java.lang.Object

org.apache.hadoop.hbase.security.visibility.VisibilityReplication

All Implemented Interfaces:

Coprocessor, RegionServerCoprocessor, RegionServerObserver

@InterfaceAudience.Private
public class VisibilityReplication
extends Object
implements RegionServerCoprocessor, RegionServerObserver

A RegionServerObserver impl that provides the custom VisibilityReplicationEndpoint. This class should be configured as the 'hbase.coprocessor.regionserver.classes' for the visibility tags to be replicated as string. The value for the configuration should be 'org.apache.hadoop.hbase.security.visibility.VisibilityController$VisibilityReplication'.
