running_maps is not decremented when the tasks of a job is killed/failed 
-------------------------------------------------------------------------

                 Key: MAPREDUCE-1158
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1158
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobtracker
    Affects Versions: 0.20.1
            Reporter: Ramya R
             Fix For: 0.20.2


running_maps counter in the metrics is not decremented when the tasks of a job is killed/failed.
Below are the exact steps to reproduce the problem:
* Initially running_maps=0
* Submit a job with 5 maps. running_maps is set to 5
* Kill 2 attempts of a map task
* Fail 4 attempts of the same map task so that the job is finally marked killed.
* Once the job is marked killed, running_maps is set to 3 and not 0.
