> TaskInProgress#kill in the JT fails because TaskStatus#setFinishTimes fails because no
start time was set. There's no start time because TaskTracker#run (DefaultTaskController#initializeJob)
failed before it was set. The fix is to have TT#launchTask set the start time before it starts
the task runner, this way there's a valid start time even if TT#run fails.
