>             Project: Mesos
>          Issue Type: Bug
>          Components: allocation, oversubscription

> We were testing a custom resource estimator which broadcasts oversubscribed resources, but they are not marked as "revocable".
> This unfortunately triggered the following check in hierarchical allocator:
> {quote}
> void HierarchicalAllocatorProcess::updateSlave(     
>   // Check that all the oversubscribed resources are revocable.
>   CHECK_EQ(oversubscribed, oversubscribed.revocable());
> {quote}
> This definitely shouldn't happen in production cluster. IMO, we should do both of following:
> 1. Make sure incorrect resource is not sent from agent (even crash agent process is better);
> 2. Decline agent registration if it's resources is incorrect, or even tell it to shutdown, and possibly remove this check.
