> Use separate threshold configurations to check when disks become full and 
> when disks become good. Currently the configuration 
> "yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage"
>  and "yarn.nodemanager.disk-health-checker.min-free-space-per-disk-mb" are 
> used to check both when disks become full and when disks become good. It will 
> be better to use two configurations: one is used when disks become full from 
> not-full and the other one is used when disks become not-full from full. So 
> we can avoid oscillating frequently.
> For example: we can set the one for disk-full detection higher than the one 
> for disk-not-full detection.
