Hi tmp, YARN doesn't provide an explicit protocol for doing this. Applications are expected to have their own mechanism for communication between task containers, other task containers, and app masters. If you want to see how this is done in MapReduce, I would suggest looking at the TaskUmbilicalProtocol, which is implemented on the AM side by TaskAttemptListenerImpl and created on the Container side in YarnChild. Through such a protocol, you could give containers the locations of other containers that would allow them to communicate correctly.
