Haibo Chen commented on YARN-7064:
----------------------------------
I deployed a pseudo-distributed cluster on a linux machine. However, the
cgroup-based resource calculator did not trigger NM to monitor a container
process.
I believe this is because
ResourceCalculatorProcessTree.getResourceCalculatorProcessTree() returns null
in isResourceCalculatorAvailable() right after
getResourceCalculatorProcessTree(String pId) is called. This is
counter-intuitive in that the cgroup-based calculator can override user defined
resource calculator, but
users also need to set cgroup-based calculator to enable container monitor with
cgroup-based resource calculator.
> Use cgroup to get container resource utilization

> to rebase patches against YARN-1011 instead of trunk.
