> URL: https://issues.apache.org/jira/browse/YARN-4768
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 3.0.0, 2.7.2
> Environment: Linux
> Reporter: Nathan Roberts
> Assignee: Nathan Roberts

>
> Algorithm currently uses "MemFree" + "Inactive" from /proc/meminfo
> "Inactive" may not be a very good indication of how much memory can be readily freed because it contains both:
> - Pages mapped with MAP_SHARED|MAP_ANONYMOUS (regardless of whether they're being actively accessed or not. Unclear to me why this is the case...)
> - Pages mapped MAP_PRIVATE|MAP_ANONYMOUS that have not been accessed recently
> Both of these types of pages probably shouldn't be considered "Available".
> "Inactive(file)" would seem more accurate but it's not available in all kernel versions. To keep things simple, maybe just use "Inactive(file)" if available, otherwise fallback to "Inactive".
