why should not capacity sheduler jar not copied under lib during build
----------------------------------------------------------------------

                 Key: MAPREDUCE-1005
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1005
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: build
    Affects Versions: 0.21.0
            Reporter: Iyappan Srinivasan


Right now, the capacity-scheduler.jar is not getting copied under 
trunk/build/hadoop-mapred-0.21.0-dev/lib/. It stays in 
trunk/build/hadoop-mapred-0.21.0-dev/contrib/capacity-scheduler/hadoop-0.21.0-dev-capacity-scheduler.jar.
  Every time somebody tries to build the trunk, they have to copy this jar from 
contrib to lib manually. 

During any kind of build (ant binary, ant bin-package, ant package) , this jar 
file should also get copied to lib. If a person uses default or fair sheduler, 
he will not use it, but still there is no harm of it being in lib. If he uses 
capacity scheduler, then it gets used automatically. This manual copy should be 
avoided.
