Subject [jira] [Updated] (HADOOP-9596) Add additional attributes to JMX beans
Date Thu, 23 May 2013 23:39:20 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-9596?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Trevor Lorimer updated HADOOP-9596:
-----------------------------------

    Description: 
Currently the JMX bean returns much of the data contained on the HDFS Health webpage (dfsHealth.html).
However there are several other attributes that are required to be added.

I intend to add the following items to the appropriate bean in parenthesis :
Started time (NameNodeInfo),
Compiled info (NameNodeInfo),
Jvm MaxHeap, MaxNonHeap (JvmMetrics)
Node Usage stats (i.e. Min, Median, Max, stdev) (NameNodeInfo),
Count of decommissioned Live and Dead nodes (FSNamesystemState),
Journal Status (NodeNameInfo)
