      Description

      Upon lost tracker, the JIP (via JobTracker.lostTracker() -> JobInProgress.failedTask()) hand crafts task status (marking the attempt as KILLED) and updates the JobInProgress (via JobInProgress.updateTaskStatus()). This status contains the attempt start time as 0. One major impact would be that the listener will overwrite the last start time value with the new one and hence the start tiem will get garbled.
