-Re: Node manager health checker opts

Unfortunately that may not be very feasible. I'll have to see if there's a
way. Are my assumptions about how the yarn.nodemanager.health-
checker.script.opts option should work correct? It took quite a bit of
trial and error to sort this out initially (who knew even an unhealthy node
script run had to have a 0 exit status...) and I'm worried I may be
starting off on the wrong foot here.
