The counts of currently running maps and reduces isn't maintained correctly when task trackers
fail
---------------------------------------------------------------------------------------------------

                 Key: HADOOP-1798
                 URL: https://issues.apache.org/jira/browse/HADOOP-1798
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.14.0
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley
             Fix For: 0.14.1


The code in JobTracker.processHeartbeat removes the task tracker status from trackerStatus
without updating the counts. Eventually the cluster will stop launching tasks.
