[jira] Created: (HADOOP-2069) DFS Summary Page
DFS Summary Page
----------------
Key: HADOOP-2069
URL: https://issues.apache.org/jira/browse/HADOOP-2069
Project: Hadoop
Issue Type: Improvement
Components: util
Reporter: Aroop Maliakkal
DFS Summary page should consists of the DFS summary data and *links* to Live Datanodes and Dead datanodes instead of loading "all nodes" information in one page. It would be great if you can give the summary in XML format also.

Are you talking about the DFS webUI dfshealth.jsp? It already has links to Live and Dead nodes. Can you pl explain in detail what you meant by "summary in XML format"? Thanks.

-----------------------------------------
We are building a dash board in which we want to put the "DFS Summary" also. We *don't* want to show Live and Dead Nodes and just the "DFS Summary" is enough. One way we can do is parsing the dfshealth.jsp and put the output in the dashboard. The problem is that every time if we are loading the dfshealth.jsp for a 2000 nodes cluster, it will put some extra load on the NameNode which we obviously want to avoid it. The current dfshealth.jsp is quite big and it takes long time to load. We are actually interested in only in "Cluster Summary" section in dfshealth.jsp page. So if you can give a xml output of *just* DFS Summary, we can include it in our dash board without putting any load on namenode and we can use the same info for some of our monitoring scripts also for checking how many nodes are *live/dead* .
Let me know if it is not clear.
