Wangda Tan commented on YARN-2868:
----------------------------------

That makes sense, but I think we still need to address this problem in the 
future, since the statistic itself is not correct.

Now my only comment is, I suggest to rename "Container First Attempt Allocation 
Delay" to "App Attempt First Container Allocation Delay".

Thanks,
Wangda
