> Ambari 2.1.0, clean install of HDP 2.2.4.2
> 1) made a config changes to yarn, changed min container size
> 2) saved, that made v2
> 3) did not do any restarts
> 4) made v1 current, which reverts and makes v3
> 5) but my restart didn't clear. I do a compare from v1 -> v3 and it shows a
> change to scheduler -- which I did not change.
> 6) it inserted this into the scheduler w/o telling me.
> yarn.scheduler.capacity.resource-calculator=org.apache.hadoop.yarn.util.resource.DefaultResourceCalculator
