Adar Dembo commented on YARN-1747:
----------------------------------
If you're willing to use the memory cgroup subsystem, you can get more accurate
RSS (i.e. w/o pages from mapped files) in memory.stat. Is that an option?
> Better physical memory monitoring for containers

> Project: Hadoop YARN
> Issue Type: Improvement
> Components: nodemanager

> YARN currently uses RSS to compute the physical memory being used by a
> container. This can lead to issues, as noticed in HDFS-5957.
