Doug Cutting commented on HADOOP-2346:
--------------------------------------
This looks nice! How well does it work?
SocketInputStream and SocketOutputStream seem like fine names, but should they
be nested classes in IOUtils, or perhaps independent classes in the 'net'
package?
Also, we might make the error messages in the exceptions a bit more
informative, e.g., including the address the socket is connected to, the
timeout, etc.
> DataNode should have timeout on socket writes.

> If a client opens a file and stops reading in the middle, DataNode thread
> writing the data could be stuck forever. For DataNode sockets we set read
> timeout but not write timeout. I think we should add a write(data, timeout)
> method in IOUtils that assumes it the underlying FileChannel is non-blocking.
