> 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.
