Sunil G commented on YARN-3254:
-------------------------------
In {{DirectoryCollection.isDiskUsageOverPercentageLimit()}}, we use
{{File#getUsableSpace}} and {{File#getTotalSpace}} to get a disk usage
information and mark disks as FULL if used size is over a threshold. So its
mostly about disk space related for now.
In latest patch, new variables are renamed to {{diskFullLocalDirsList}} etc.
> HealthReport should include disk full information

> When a NodeManager's local disk gets almost full, the NodeManager sends a
> health report to ResourceManager that "local/log dir is bad" and the message
> is displayed on ResourceManager Web UI. It's difficult for users to detect
> why the dir is bad.
