Hi Samir, could you share the logs of the two JMs and the log where you saw the FencingTokenException with us?
It looks to me as if the TM had an outdated fencing token (an outdated leader session id) with which it contacted the ResourceManager. This can happen and the TM should try to reconnect to the RM once it learns about the new leader session id via ZooKeeper. You could, for example check in ZooKeeper that it contains the valid leader information.
