Subject [jira] [Created] (MAPREDUCE-4936) JobImpl uber checks for cpu are wrong
Date Fri, 11 Jan 2013 16:58:12 GMT
Daryn Sharp created MAPREDUCE-4936:

             Summary: JobImpl uber checks for cpu are wrong
                 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
            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 {{<=}}


    boolean smallCpu =
                conf.getInt(MRJobConfig.MAP_CPU_VCORES, 1), 
                conf.getInt(MRJobConfig.REDUCE_CPU_VCORES, 1)) < 

Everything is defaulting to 1, so uber cpu checks are now disabled causing {{TestUberAM}}
to fail.
