> Check unreachable task cache for task ID collisions on launch

> Key: MESOS-6805
> URL: https://issues.apache.org/jira/browse/MESOS-6805
> Project: Mesos
> Issue Type: Bug
> Components: master
> Reporter: Neil Conway
> Assignee: Neil Conway
> Labels: mesosphere
>
> As discussed in MESOS-6785, it is possible to crash the master by launching a
> task that reuses the ID of an unreachable/partitioned task. A complete
> solution to this problem will be quite involved, but an incremental
> improvement is easy: when we see a task launch operation, reject the launch
> attempt if the task ID collides with an ID in the per-framework
> {{unreachableTasks}} cache. This doesn't catch all situations in which IDs
> are reused, but it is better than nothing.
