Description

After activating yarn.nodemanager.container-monitor.procfs-tree.smaps-based-rss.enabled nodemanagers are reporting lots of parsing error like this one

Error in parsing : INVALID : valuerd wr mr mw me ac

Looking at smaps file I can see that there are in fact one line with no Number:

VmFlags: rd ex mr mw me de

This line is retreived by the MEM_INFO_PATTERN in ProcfsBasedProcessTree
