Subject Re: strange behavior of spark 2.1.0

Thank you for replying. 
Actually there is no any message coming during the exception. And there is no OOME in any
executor. What I am suspecting it might be caused by AWL.

BTW I have customized receiver, I either do not think it is happened from receiver, there
is no any error exception from receiver, and I can also track the stop command is sent from
"onStop" function in receiver.
