---------------------------------------
Summary: Race between operation status updates and agent update
Key: MESOS-8430
URL: https://issues.apache.org/jira/browse/MESOS-8430
Project: Mesos
Issue Type: Task
Components: agent
Reporter: Benjamin Bannier
Currently, there exists a possible race between operation status updates
triggered by a status update manager in the agent and updates to the agent's
resources.
Consider a master failover where an agent has a resource provider with an
operation which was not terminal. Now let the operation succeed and become
terminal in the agent, but have the master failover before it processes the
update. After master failover, the new master would learn about the resource
provider resources via an `UpdateSlaveMessage`. Simultaneously, a status update
manager in the agent could inform the master about the unacknowledged,
successful operation. If the operation status update arrives in the master
before the `UpdateSlaveMessage`, the operation status update handler could
attempt to apply the operation on resources unknown to it, yet. This would
likely trigger a `CHECK` failure in a contains check.
