             Summary: Race between executor exited event and launch task can cause overcommit of resources
                 Key: MESOS-1466
                 URL: https://issues.apache.org/jira/browse/MESOS-1466
             Project: Mesos
          Issue Type: Bug
            Reporter: Vinod Kone


The following sequence of events can cause an overcommit

--> Launch task is called for a task whose executor is already running

--> Executor's resources are not accounted for on the master

--> Executor exits and the event is enqueued behind launch tasks on the master

--> Master sends the task to the slave which needs to commit for resources for task and the (new) executor.

--> Master processes the executor exited event and re-offers the executor's resources causing an overcommit of resources.
