Subject [jira] Commented: (HADOOP-4756) Create a command line tool to access JMX exported properties from a NameNode server
Date Thu, 05 Mar 2009 02:13:56 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4756?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12679038#action_12679038
] 

he yongqiang commented on HADOOP-4756:
--------------------------------------

Can we use jconsole or other tools for this?

I remember that in hadoop 0.17, jconsole  can not connect to hadoop NameNode daemon, DataNode
daemon, because there is no JMXConnectorServer in there. So in hadoop 0.17, what I did is
to add some JMXConectorServer code myslef, with which i can use jconsol for monitoring.  Because
those code is not licensice compatible, so i did not commit that. 
Has that been added officially now?
