> This JIRA is to request opinion from the community, Can new file system use an extension
of WebHDFS file system. 
> Considering all the known limitation WebHDFS has over implementing a new client by extending
FileSystem class.
> Option we have is 
> 1. Use the namespace org.apache.hadoop.hdfs.web in new file system implementation to
access protected functionality from WebHdfsFileSystem.
> 2. Change the WebHdfs to support extensions
> 3. Suggestion on different approach like new client by sub classing FileSystem.
