---------------------------------------
> Is there any value in letting exceptions out of a close? What will the
> application do with an exception thrown on a close?
The application can know that the data it wrote to the file could be bad and
trigger appropriate recovery. In fact, it is very important that this
exception be thrown to the applications instead of silently ignoring it.
> DFSClient.close doesn't rethrow exceptions thrown by automatically closed
> clients

> I've written a fault injection test that simply throws exceptions on every
> ack.readFields call in ResponseProcessor. This ought to raise an exception to
> the client trying to use the stream, but instead it ignores it silently.
