MENG DING commented on YARN-1197:
---------------------------------
[~sandyr], by processing both resource decrease and increase request through
RM, the original problem that I brought up should not be an issue any more.
What we are trying to grasp right now is if it is really necessary for the
increase action to go through RM->AM->NM. IMHO, if we can eliminate the need
for that while still achieving reasonable performance, that would be ideal.

> Key: YARN-1197
> URL: https://issues.apache.org/jira/browse/YARN-1197
> Project: Hadoop YARN
> Issue Type: Task
> Components: api, nodemanager, resourcemanager
> Affects Versions: 2.1.0-beta
> Reporter: Wangda Tan

> 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
