             Summary: DRF allocator crashes master with CHECK when resource is incorrect
                 Key: MESOS-5131
                 URL: https://issues.apache.org/jira/browse/MESOS-5131
             Project: Mesos
          Issue Type: Bug
          Components: allocation, oversubscription
            Reporter: Zhitao Li
            Priority: Critical


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.
