> Whenever I try to start a MiniYARNCluster on Branch-2 (commit #0b61cca), I see multiple
stack traces warning me that a resource calculator plugin could not be created
> {code}
> (ResourceCalculatorPlugin.java:getResourceCalculatorPlugin(184)) - java.lang.UnsupportedOperationException:
Could not determine OS: Failed to instantiate default resource calculator.
> java.lang.UnsupportedOperationException: Could not determine OS
> {code}
> This is a minicluster. It doesn't need resource calculation. It certainly doesn't need
test logs being cluttered with even more stack traces which will only generate false alarms
about tests failing. 
> There needs to be a way to turn this off, and the minicluster should have it that way
by default.
> Being ruthless and marking as a blocker, because its a fairly major regression for anyone
testing with the minicluster.
