Description

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.
