Description

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.
