Jan Lukavsky created YARN-4681: ---------------------------------- Summary: ProcfsBasedProcessTree should not calculate private clean pages Key: YARN-4681 URL: https://issues.apache.org/jira/browse/YARN-4681 Project: Hadoop YARN Issue Type: Improvement Components: nodemanager Affects Versions: 2.7.0, 2.6.0 Reporter: Jan Lukavsky
ProcfsBasedProcessTree in Node manager calculates memory used by a process tree by parsing `/etc/<pid>/smaps`, where it calculates `min(Pss, Shared_Dirty) + Private_Dirty + Private_Clean`. Because not `mlocked` private clean pages can reclaimed by kernel, this should be changed to calculating only `Locked` pages instead. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
