Eric Badger commented on YARN-9809:
-----------------------------------

Good catch, [~Jim_Brennan]. {{updateMetricsForRejoinedNode()}} is only called 
in one other place and I don't want to add the node and then remove it again. 
So I removed the increment from {{updateMetricsForRejoinedNode()}} and 
explicitly added it to just before the other place where 
{{updateMetricsForRejoinedNode()}} is called.

> 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.
