------------------------------------------------------------
[~leftnoteasy], so with respect to protobuf changes, we havn't removed
anything, only added new fields. And with regard to the Java API, again, we
havn't removed any of the old API's - we've just marked them as deprecated, and
internally route then thru the new API.
Also, we want to target these for 2.9.x and 3.x. Let me know if you require
them for 2.8.x and we can dig further into compatibility issues before we
cherry-pick it there.

> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Arun Suresh
> Assignee: kartheek muthyala
> Fix For: 2.9.0, 3.0.0-beta1

> Currently, only the Container Resource decrease command is sent to the NM via
> NodeHeartbeat response. This JIRA proposes to add a flag in the RM to allow
> ALL container updates (increase, decrease, promote and demote) to be
> initiated via node HB.
> The AM is still free to use the ContainerManagementPrototol's
> {{updateContainer}} API in cases where for instance, the Node HB frequency is
> very low and the AM needs to update the container as soon as possible. In
> these situations, if the Node HB arrives before the updateContainer API call,
> the call would error out, due to a version mismatch and the AM is required to
> handle it.
