------------------------------------
Issue Type: Bug (was: Task)
> Race between operation status updates and agent update
> ------------------------------------------------------
>
> Key: MESOS-8430
> URL: https://issues.apache.org/jira/browse/MESOS-8430
> Project: Mesos
> Issue Type: Bug
> Components: agent
> Affects Versions: 1.5.0
> 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 in the master.
