> In current code, timeout is not specified when JobTracker (JobEndNotifier)
> calls into the notification URL. When the given URL points to a server that
> will not respond for a long time, job notifications are completely stuck
> (given that we have only a single thread processing all notifications). We've
> seen this cause noticeable delays in job execution in components that rely on
> job end notifications (like Oozie workflows).
> I propose we introduce a configurable timeout option and set a default to a
> reasonably small value.
> If we want, we can also introduce a configurable number of workers processing
> the notification queue (not sure if this is needed though at this point).
> I will prepare a patch soon. Please comment back.
