  If a task absolutely must break the rules, there are a few things one can do:

   * Deploy ZooKeeper and use it as a persistent lock to keep track of how many tasks are running concurrently
   * Use a scheduler with a maximum task-per-queue feature and submit the job to that queue, such as FairShareScheduler or CapacityScheduler
