> Steps to reproduce:
> * Start YARN cluster - Enable Opportunistic containers and set NM queue length to something
> 10. Also Enable work preserving restart
> * Start an MR job (without opportunistic containers)
> * Kill the NM and restart it again.
> * In the logs - it shows that some of the containers are in SUSPENDED state - even though
they are still running.
