> While validating some HA failure modes we found that HDFS clients can take a
> long time to recover or sometimes don't recover at all since we don't setup
> the socket timeout in the InputStream:
> {code}
> private void transfer () { ...
> ...
> OutputStream unbufOut = NetUtils.getOutputStream(sock, writeTimeout);
> InputStream unbufIn = NetUtils.getInputStream(sock);
> ...
> }
> {code}
> The InputStream should have its own timeout in the same way as the
> OutputStream.
