I'm using AWS EMR with Hadoop and Yarn and when I go to UI of the RM I can see information like "Physical Mem Used %" and "Physical VCores Used %". I cannot find anything online (on Web) for these values and I need to understand what they stand for exactly.
Also if I go to /ws/v1/cluster/metrics
I can see on XML files like "utilizedMBPercent" & "utilizedVirtualCoresPercent" which represent those two mentioned above. When no Job is running "utilizedMBPercent" is on 13% and "utilizedVirtualCoresPercent" on Zero.
This is also info that I can see: hadoop-yarn-resourcemanager 3.3.3-amzn-4
Can someone please explain to me those two values.
