Correct, MR throws an exception, but again a lot of that is legacy from
hadoop 1.x when it was the only thing running. The auxiliary services were
added just for that originally. You could very well argue its a bug there too.
So you are seeing users hit the max number of executor failures then?
Without blacklisting I can definitely see this as an issue.
The other question is why is it failing to start on the NM? is it port
conflict like you mentioned or is it just something bad happened on one node?
