JMXListener (Apache HBase 1.2.12 API)

java.lang.Object
- org.apache.hadoop.hbase.JMXListener

All Implemented Interfaces:

Coprocessor
```
public class JMXListener
extends Object
implements Coprocessor
```
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)
