> If Tez Container Size or VCores is an invalid value ( <= 0 ) then it falls back onto the MapReduce configurations, but if the MapReduce configurations have invalid values ( <= 0 ), they are excepted regardless and this will cause failures down the road.
> This code should also check the MapReduce values and fall back to MapReduce default values if they are <= 0.
> Also, some logging would be nice here too, reporting about where the configuration values came from.
