>
> ClientProtocol can be simplified by removing two methods
> {code}
> public boolean exists(String src) throws IOException;
> public boolean isDir(String src) throws IOException;
> {code}
> This is a redundant api, which can be implemented in DFSClient as convenience methods
using
> {code}
> public DFSFileInfo getFileInfo(String src) throws IOException;
> {code}
> Note that we already deprecated several Filesystem method and advised to use getFileStatus()
instead.
> Should we deprecate them in 0.16?
