> Currently, only the Container Resource increase 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 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.
