--------------------------------
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.
