Devaraj K commented on SPARK-19354:
-----------------------------------

Thanks [~uncleGen] for the comment. Here the error occurred during the kill 
process is masking the original reason that the task has been killed, I think 
we need to retain the real reason instead of the masked one. And also when we 
see a failed task we may suspect something went wrong and starts diagnose for 
the cause, finally we see that it happened during kill. It also shows wrong 
metrics in the section 'Aggregated Metrics by Executor'.

> Killed tasks are getting marked as FAILED
