Todd Lipcon commented on HADOOP-8350:
-------------------------------------
This isn't a public API:
{code}
@InterfaceAudience.LimitedPrivate({"HDFS", "MapReduce"})
@InterfaceStability.Unstable
public class NetUtils {
private static final Log LOG = LogFactory.getLog(NetUtils.class);
{code}
It looks like you're using a binary built against a different version than
you're running against.
> Improve NetUtils.getInputStream to return a stream which has a tunable timeout

> Currently, NetUtils.getInputStream will set the timeout on the new stream
> based on the socket's configured timeout at the time of construction. After
> that, the timeout cannot be changed. This causes a problem for cases like
> HDFS-3357. One approach used in some places in the code is to construct new
> streams when the timeout has to be changed, but this can cause bugs given
> that the streams are often wrapped by BufferedInputStreams.
