> When NM is unable to connect to RM, NM shuts itself down.
> {code}
> } catch (ConnectException e) {
> //catch and throw the exception if tried MAX wait time to connect
> RM
> dispatcher.getEventHandler().handle(
> new NodeManagerEvent(NodeManagerEventType.SHUTDOWN));
> throw new YarnRuntimeException(e);
> {code}
> In large clusters, if RM is down for maintenance for longer period, all the
> NMs shuts themselves down, requiring additional work to bring up the NMs.
> Setting the yarn.resourcemanager.connect.wait-ms to -1 has other side
> effects, where non connection failures are being retried infinitely by all
> YarnClients (via RMProxy).
