> Just as YARN-6212. However, I think it is not a duplicate of YARN-3933.
> The primary cause of negative values is that metrics do not recover properly
> when NM restart.
> AllocatedContainers,ContainersLaunched,AllocatedGB,AvailableGB,AllocatedVCores,AvailableVCores
> in metrics also need to recover when NM restart.
> This should be done in ContainerManagerImpl#recoverContainer.
> The scenario could be reproduction by the following steps:
> # Make sure
> YarnConfiguration.NM_RECOVERY_ENABLED=true,YarnConfiguration.NM_RECOVERY_SUPERVISED=true
> in NM
> # Submit an application and keep running
> # Restart NM
> # Stop the application
> # Now you get the negative values
