Eric Payne commented on YARN-9809:
----------------------------------
Thanks a lot [~ebadger] for putting upt the 3.2 backport patch. I'm still going
through it, but I had one question after my first pass:
{code:java|title=RMNodeImpl#AddNodeTransition#transition}
RMNodeStatusEvent rmNodeStatusEvent =
new RMNodeStatusEvent(nodeId, nodeStatus);
NodeHealthStatus nodeHealthStatus =
updateRMNodeFromStatusEvents(rmNode, rmNodeStatusEvent);
if (nodeHealthStatus.getIsNodeHealthy()) {
{code}
Do we run the risk of {{nodeHealthStatus}} being null?
> NMs should supply a health status when registering with RM

> Currently if the NM registers with the RM and it is unhealthy, it can be
> scheduled many containers before the first heartbeat. After the first
> heartbeat, the RM will mark the NM as unhealthy and kill all of the
> containers.
