> [YARN-3943] added separate configurations for the nodemanager health check
> disk utilization full disk check:
> {{max-disk-utilization-per-disk-percentage}} - threshold for marking a good
> disk full
> {{disk-utilization-watermark-low-per-disk-percentage}} - threshold for
> marking a full disk as not full.
> On our clusters, we do not use these configs. We instead use
> {{min-free-space-per-disk-mb}} so we can specify the limit in mb instead of
> percent of utilization. We have observed the same oscillation behavior as
> described in [YARN-3943] with this parameter. I would like to add an optional
> config to specify a separate threshold for marking a full disk as not full:
> {{min-free-space-per-disk-mb}} - threshold at which a good disk is marked full
> {{disk-free-space-per-disk-high-watermark-mb}} - threshold at which a full
> disk is marked good.
> So for example, we could set {{min-free-space-per-disk-mb = 5GB}}, which
> would cause a disk to be marked full when free space goes below 5GB, and
> {{disk-free-space-per-disk-high-watermark-mb = 10GB}} to keep the disk in the
> full state until free space goes above 10GB.
