Eric Yang commented on YARN-9809:
---------------------------------
[~ebadger] It is unlikely to determine unhealthy status until at least one
container tried to run on the given node manager. How does health status field
in registration heartbeat help? If containers are getting killed, they are
supposed to schedule else where. Do you observe any problem in rescheduling
containers?

> Currently if the NM registers with the RM and it is unhealthy, it can be
