Subject [jira] [Commented] (HBASE-10289) Avoid random port usage by default JMX Server. Create Custome JMX server
Date Fri, 30 May 2014 17:21:02 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10289?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14013968#comment-14013968
] 

stack commented on HBASE-10289:
-------------------------------

[~tianq] Thank you for the nice patch and excellent doc!  Should bin/hbase-env.sh comments
be amended around JMX?  Does the old way of setting up JMX will work?  If so, should the doc
mention it as alternative (though refer back to why it is inferior) and should bin/hbase-env.sh
comments point into the hbase refguide for an alternative that allows setting explicit, unchanging
ports?

Nice work [~tianq]

> 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.
