Class JMXListener

java.lang.Object

org.apache.hadoop.hbase.JMXListener

All Implemented Interfaces:

org.apache.hadoop.hbase.Coprocessor, MasterCoprocessor, RegionServerCoprocessor

@InterfaceAudience.Private
public class JMXListener
extends Object
implements MasterCoprocessor, RegionServerCoprocessor

Pluggable JMX Agent for HBase(to fix the 2 random TCP ports issue of the out-of-the-box JMX Agent): 1)connector port can share with the registry port if SSL is OFF 2)support password authentication 3)support subset of SSL (with default configuration)
