Is this going on?
"I was wondering if this issue can be easily finished by writing a custom
health checker script (idea from YARN-9923).
I think it would make sense to push this feature - would you like to share your
PoC and compare its advantages/disadvantages to a node checker script?"
This is a good suggestion.

> Issue Type: Sub-task
> Reporter: Zhankun Tang
> Assignee: Zhankun Tang
> Priority: Major
>
> We have GPU resource discovered when the NM bootstrap but not updated through
> later heatbeat with RM. There should be a monitoring mechanism to check GPU
> healthy status from time to time and also the corresponding handling.
> And YARN-8851 will also handle device's monitoring. There could be some
> common part between the two.
