Subject [jira] [Commented] (HBASE-10289) Avoid random port usage by default JMX Server. Create Custome JMX server
Date Fri, 04 Apr 2014 21:13:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10289?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13960426#comment-13960426
] 

Demai Ni commented on HBASE-10289:
----------------------------------

[~saint.ack@gmail.com], the patch looks good to me.
I configured hbase-site.xml by adding : 
{code}
<property>
 <name>hbase.master.rmi.registry.port</name>
 <value>2356</value>
</property>
<property>
 <name>hbase.regionserver.rmi.registry.port</name>
 <value>2357</value>
</property>
{code}
and both ports are set on my single-node cluster. 

the patch is out of date, I will upload a new one shortly

> 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.
