MENG DING updated YARN-1197:
----------------------------
    Attachment: YARN-1197_Design.2015.06.24.pdf

The design doc has been updated based on the latest discussion and feedback 
from all parties. I have added a section for NodeManager recovery as well. Some 
details still need to be ironed out, which will be covered in sub-tasks. 
Special thanks to [~leftnoteasy] for all the valuable suggestions offline.

> The current YARN resource management logic assumes resource allocated to a 
> container is fixed during the lifetime of it. When users want to change a 
> resource 
> of an allocated container the only way is releasing it and allocating a new 
> container with expected size.
> Allowing run-time changing resources of an allocated container will give us 
> better control of resource usage in application side
