>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: scheduler
>    Affects Versions: 2.0.3-alpha
>            Reporter: Thomas Graves
>            Assignee: Zhijie Shen
>         Attachments: YARN-382_1.patch, YARN-382_demo.patch
> In YARN-370, we changed it from setting the capability to directly setting memory and
> -    ask.setCapability(normalized);
> +    ask.getCapability().setMemory(normalized.getMemory());
> +    ask.getCapability().setVirtualCores(normalized.getVirtualCores());
> We did this because it is directly setting the values in the original resource object
passed in when the AM gets allocated and without it the AM doesn't get the resource normalized
correctly in the submission context. See YARN-370 for more details.
> I think we should find a better way of doing this long term, one so we don't have to
keep adding things there when new resources are added, two because its a bit confusing as
to what its doing and prone to someone accidentally breaking it in the future again.  Something
closer to what Arun suggested in YARN-370 would be better but we need to make sure all the
places work and get some more testing on it before putting it in.
