> The HDFS health screen (dfshealth.jsp) displays basic Version, Security and 
> Health information concerning the NameNode, currently this information is 
> accessible from classes in the org.apache.hadoop,hdfs.server.namenode package 
> and cannot be accessed outside the NameNode. This becomes prevalent if the 
> data is required to be displayed using a new user interface.
> The proposal is to create a REST interface to expose all the information 
> displayed on dfshealth.jsp using GET methods. Wrapper classes will be created 
> to serve the data to the REST root resource within the hadoop-hdfs project.
> This will enable the HDFS health screen information to be accessed remotely.
