> 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.
