[jira] [Commented] (SPARK-12009) Avoid re-allocate yarn container
while driver want to stop all Executors
[ https://issues.apache.org/jira/browse/SPARK-12009?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16045364#comment-16045364 ]
lida commented on SPARK-12009:
------------------------------
AsynchronousListenerBus class
def post(event: E) {
if (stopped.get) {
// Drop further events to make `listenerThread` exit ASAP
logError(s"$name has already stopped! Dropping event $event")
return
}
val eventAdded = eventQueue.offer(event)
if (eventAdded) {
eventLock.release()
} else {
onDropEvent(event)
}
}
I think "* has already stopped! Dropping event *" is a success finished event，before sent the event to the queue, and the log use the logError(s"$name has already stopped! Dropping event $event").
