Vinod Kone commented on MESOS-1454:
-----------------------------------

Can we skip the containerizer->update() if its a command executor task?

> The command executor is used when TaskInfo does not provide an ExecutorInfo. It is not given any dedicated resources but the executor will be launched with the first task's resources. However, assuming a single task (or a final task), when that task terminates the container will be updated to zero resources - see containerizer->update in Slave::statusUpdate().
> Possible solutions:
> - Require a task to specify an executor and resources for it.
> - Add sufficient allowance for the command executor beyond the task's resources. This leads to an overcommit.
