Raghu Angadi updated HADOOP-2346:
---------------------------------
Attachment: HADOOP-2346.patch
This patch implements write timeout on datanodes for block reads. Currently
only client reads have write timeout. Once the fix looks good , we can write
timeout in other places (while writing mirror for e.g.).
This adds two classes SocketInputStream and SocketOutputStream in IOUtils.
Please suggest better names.
> 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.
