In our application the "client" is actually one step of many in an application. If the "client" goes away entirely, that means the entire application has crashed or has been terminated somehow. Our application doesn't checkpoint state at this step, so the step will have to be restarted anyway. This doesn't break anything, it is just a waste to let it keep running. Thanks for clarifying the stateless nature of the client connection. John

The architecture is built around detachable clients. So, no, it doesn't happen automatically. Even if we were to add that feature, it'd be fraught with edge cases - network issues causing app-termination even though client is still alive etc. Any more details on why this is desired? +Vinod On Jan 11, 2014, at 11:37 AM, John Lilley <[email protected]<mailto:[email protected]>> wrote: We have a YARN application that we want to automatically terminate if the YARN client disconnects or crashes. Is it possible to configure the YarnClient-RM connection so that if the client terminates the RM automatically terminates the AM? Or do we need to build our own logic (e.g. a direct client-AM connection) for that?
