------------------------------------------
My bad - I'm pretty sure these passed when I ran it initially. IAC, I'll fix this. Thanks for pointing it out Daryn.

> Key: MAPREDUCE-4936
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4936
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 3.0.0, 2.0.3-alpha
> Reporter: Daryn Sharp
> Assignee: Arun C Murthy
> Priority: Critical
>
> The cpu checks for uberizing have two issues:
> # the defaults are hardcoded instead of using the conf defaults
> # the comparison against the sys cpu size is using {{<}} instead of {{<=}}
> {code}
> boolean smallCpu =
> (
> Math.max(
> conf.getInt(MRJobConfig.MAP_CPU_VCORES, 1),
> conf.getInt(MRJobConfig.REDUCE_CPU_VCORES, 1)) <
> sysCPUSizeForUberSlot
> );
> {code}
> Everything is defaulting to 1, so uber cpu checks are now disabled causing {{TestUberAM}} to fail.
