Zhijie Shen commented on YARN-486:
----------------------------------
@Bikas, I agree it would be more elegant to embed a container directly in CLC.
However, one issue found when I did this attempt is that a "fake" container for
AM need to created before submitting the application. In contrast, other
containers that will be put into CLC are all actually allocated. Therefore,
IMHO, the "fake" container should be specially treated.
> Change startContainer NM API to accept Container as a parameter and make
> ContainerLaunchContext user land

> Currently, id, resource request etc need to be copied over from Container to
> ContainerLaunchContext. This can be brittle. Also it leads to duplication of
> information (such as Resource from CLC and Resource from Container and
> Container.tokens). Sending Container directly to startContainer solves these
> problems. It also makes CLC clean by only having stuff in it that it set by
> the client/AM.
