The design doc has been updated to include a *Design Choices* section, which
summarizes the rationales behind major design decisions.
Patches to {{NodeManager}} side of the implementation have been posted for
review, which include:
YARN-1449: AM-NM protocol changes to support container resizing
YARN-1645: ContainerManager implementation to support container resizing
YARN-3867: ContainerImpl changes to support container resizing
YARN-1643: ContainersMonitor changes to support monitoring/enforcing container
resizing
YARN-1644: RM-NM protocol changes and NodeStatusUpdater implementation to
support container resizing
YARN-3868: ContainerManager recovery for container resizing
In addition, YARN-3866 has been posted for review to unblock RM/Scheduler
changes in YARN-1651 and YARN-1646.
> Support changing resources of an allocated container

> Key: YARN-1197

> Project: Hadoop YARN
> Issue Type: Task
> Components: api, nodemanager, resourcemanager
> Affects Versions: 2.1.0-beta
> Reporter: Wangda Tan
> Attachments: YARN-1197 old-design-docs-patches-for-reference.zip,

>
> 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
