----------------------------------
Thanks [~kkaranasos] for updating the patch
bq. Just double-checking: do you mean adding an additional description in the
javadoc of the ExecutionType?
Yes
And:
{code}
87 @Public
88 @Stable
89 public static ResourceRequest newInstance(Priority priority, String
hostName, ...
{code}
Should be unstable as well.

on YARN-1011:
bq. Given this complication, I would prefer we do not involve AMs in the
decision-making process. Based on the need and usecases, we could revisit this
at a later time. Note that YARN-4335 adds this to ResourceRequest for
distributed scheduling, and even there they are not entirely sure if it needs
to be a part.
I'm not sure if there's any tasks of YARN-2877 directly depends on it, It's
fine to me to commit this to YARN-2877 branch, but I prefer to hold commit
unless any tasks require it.

> YARN-2882 introduced container types that are internal (not user-facing) and
> are used by the ContainerManager during execution at the NM.
> With this JIRA we are introducing (user-facing) resource request types that
> are used by the AM to specify the type of the ResourceRequest.
> We will initially support two resource request types: CONSERVATIVE and
> OPTIMISTIC.
> CONSERVATIVE resource requests will be handed internally to containers of
> GUARANTEED type, whereas OPTIMISTIC resource requests will be handed to
> QUEUEABLE containers.
