> Key: GIRAPH-1230
> URL: https://issues.apache.org/jira/browse/GIRAPH-1230
> Project: Giraph
> Issue Type: Bug
> Reporter: Dionysios Logothetis
> Assignee: Dionysios Logothetis
> Priority: Major
>
> - The LogOnErrorChannelFutureListener is called when a channel operation was
> complete and it was checking whether the channel failed, in which case it
> tried to resend any requests. Doing this required to wait until a channel had
> been re-established. However, doing a wait operation from the same thread
> that calls the handler, causes a BlockingOperationException from Netty. So
> this is not effective.
> - Upon a channel closing, we have logic that will try to re-open the channels
> doing a max number of retries.. But we also had logic in the ChannelRoterator
> that would throw an exception if we didn't find any channel. This does not
> give the opportunity to re-conenct.
> - Whenever the client closes the connection, the server catches this
> (Connection reset by peer) and throws an exception as well, so the job fails
> immediately. This does not give the opportunity to the client to re-connect.
