Description

The MBeans class in hadoop-common helps to register MXBean to the platform jmx bean. Unfortunatelly it supports only Name and Service keys even if the JMX specification allows any key value pairs to use as a part of the ObjectName.

This patch adds the possibility to define more key/value pairs for the JMX ObjectName.

It will be usefull for the SCM/KSM web page. Both SCM/KSM Server have common jmx properties. But to use a common html component to display them we need a possibility to get the JMX bean of SCM server and KSM server with one query.

This will be possible with adding additional (common) key/value property to the ObjectName.
