Bikas Saha commented on YARN-1197:
----------------------------------

The API supports it but the backed implementation does not. So in the future, 
based on need, this could be supported compatibly. Do you have a scenario where 
this is essential?

> 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
