so I'm trying to understand exactly when this affects performance. I saw
in the jira you saw its when you use java word count. So is this only an issue
when things do a collect back to the ApplicationMaster or does it affect all
driver performance? 2x seems huge for just having the securityManager there.
SIGH.. thats unfortunate. We should basically revert back to the 1.1
behavior which is to mark things as succeeded even though they may have failed.
