      Description

      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.
