I'm not sure what's wrong with the HDFS pre-commit build. This patch builds for
me locally.
Thanks again, [~kihwal].

> In the current implementation of WebHdfsFileSystem, opens are retried
> according to the configured retry policy, but not reads. Therefore, if a
> connection goes down while data is being read, the read will fail and the
> read will have to be retried by the client code.
> Also, after a connection has been established, the next read (or seek/read)
> will fail and the read will have to be restarted by the client code.
