Resolution: Duplicate
Same discussion going on in HDFS-6633. So duplicating it.

> DFSInputStream

> Currently DFSInputStream can read only till the bytes written which were
> written by the time of Opening it for reading.
> But, later there can be more bytes written to same file.
> If client expects more data to be available, then client can poll it
> continuously for more data without re-opening the stream.
> One simple example use case for this is tailing logs files.
> Currently LocalFileSystem supports this.
