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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
