[jira] [Commented] (HBASE-10289) Avoid random port usage by default JMX Server. Create Custome JMX server

Qiang Tian commented on HBASE-10289:
------------------------------------

Hi guys,
sorry for late response.  
the new patch just uploaded is a pluggable solution based on coprocessor, so that user could turn off or switch back easily.
1)support password authentication

2)support a subset of SSL(Enforcing SSL for communication
) with default configuration.  see http://ddweerasiri.blogspot.com/2011/08/ssl-enabled-jconsole-to-monitor-wso2.html for example.

3)registry port and connector port can be configured separately. or combined into 1 when SSL is not enabled. (If SSL is enabled, the connector port must use a different value than registry port)

4)only load coprocessor for regionserver, since "master is also a regionserver" in 0.99.

5)the code references the example on official site: http://docs.oracle.com/javase/7/docs/technotes/guides/management/agent.html (see section "Example of Mimicking Out-of-the-Box Management")

6)password authentication and SSL test are done manually since the code almost does nothing for it - most work is related to environment

7)confirmed random port issue is not resolved in JDK 7 unless bug 8035404 is fixed.

appreciate your comments.
thanks.

> If we enable JMX MBean server for HMaster or Region server  through VM arguments, the process will use one random which we cannot configure.
> This can be a problem if that random port is configured for some other service.
> This issue can be avoided by supporting  a custom JMX Server.
> The ports can be configured. If there is no ports configured, it will continue the same way as now.
