Michael Park commented on MESOS-7714:
-------------------------------------
In order to support (1) I think we'd have to checkpoint resources with refined
reservations in a different location.
You're saying you wouldn't want to upgrade to 1.4 because you can't downgrade
once people start using new features?
Just for comparison, we have the same limitations for multi-role support. That
is, once you upgrade to 1.3 and
and frameworks start using multi-role, you can't downgrade.

> Project: Mesos
> Issue Type: Bug
> Reporter: Michael Park
> Priority: Blocker
>
> The agent code only partially supports downgrading of an agent correctly.
> The checkpointed resources are done correctly, but the resources within
> the {{SlaveInfo}} message as well as tasks and executors also need to be
> downgraded
> correctly and converted back on recovery.
