[jira] Resolved: (HADOOP-250) HTTP Browsing interface for DFS
Health/Status
[ http://issues.apache.org/jira/browse/HADOOP-250?page=all ]
Doug Cutting resolved HADOOP-250:
---------------------------------
Resolution: Fixed
I just committed this. I made two additional changes. In FSNameSystem.java I moved the initialization of the static variable fsNameSystemObject to before where Jetty is started, since the jsp pages require a non-null value for this and the servlet init was failing with a null pointer exception. I also added an entry to hadoop-default.xml for the new dfs.info.port parameter.

> A web interface to view the DFS health/status (name and data nodes) is to be created. User can connect to the webserver on the namenode and a web page will be displayed. The web page will give some details about that namenode (startup time and the total cluster capacity). The web page will contain a table of 'live' and 'dead' datanodes. Each live datanode will be a link to the complete details of the datanode as given by DatanodeInfo (also see DataNodeReport).
