Hitesh Shah commented on YARN-572:
----------------------------------
Assuming that the ContainerToken is going to be changed into a bytebuffer to
hide from the AM, the duplication of fields will be necessary.
@Sid, @Vinod, can you confirm on the bytebuffer change? In that case, we can
close this jira out.
> Remove duplication of data in Container

> Most of the information needed to launch a container is duplicated in both
> the Container class as well as in the ContainerToken object that the
> Container object already contains. It would be good to remove this level of
> duplication.
