> Prior to federation datanode had only one namenode. In servlets hosted on
> datanode, a DFSClient was created to the only namenode to serve the request.
> However with federation datanode has multiple namenodes. When a request is
> redirected to a datanode, it does not know which namenode to use for
> servicing the request.
> This results in TestHftpFileSystem failure.
