> There seems to be a bug in {{TaskInProgress.taskKilled}} which checks if that taskid
was in {{tasksToKill}}, if not, it just marks the taskid as FAILED. This is wrong since tasks
can also be KILLED due to *lost task-trackers* and hence won't be found in {{tasksToKill}}.
> This clearly leads to a wrongly penalizing user-jobs.
