MENG DING commented on YARN-1197:
---------------------------------
[~sandflee], for now you can achieve the goal of increasing and decreasing
different resource indices by sending separate resource change requests, with
each request only changing one index.
> Support changing resources of an allocated container

> Key: YARN-1197
> URL: https://issues.apache.org/jira/browse/YARN-1197
> Project: Hadoop YARN
> Issue Type: Task
> Components: api, graceful, 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
