• Type: Bug

• Fix Version/s: 0.98.13, 1.0.2, 1.2.0, 1.1.1, 2.0.0
• Component/s: master, metrics
• Hadoop Flags: Reviewed

Release Note

To use the coprocessor-based JMX implementation provided by HBase for Master.
Add below property in hbase-site.xml file:

<property>
  <name>hbase.coprocessor.master.classes</name>
  <value>org.apache.hadoop.hbase.JMXListener</value>
</property>

NOTE: DO NOT set `com.sun.management.jmxremote.port` for Java VM at the same time.

By default, the JMX listens on TCP port 10101 for Master, we can further configure the port using below properties:

<property>
  <name>master.rmi.registry.port</name>
  <value>61110</value>
</property>
<property>
  <name>master.rmi.connector.port</name>
  <value>61120</value>
</property>
----

The registry port can be shared with connector port in most cases, so you only need to configure master.rmi.registry.port.
However if you want to use SSL communication, the 2 ports must be configured to different values.
