Ian Downes created MESOS-1454:
---------------------------------
Summary: Command executor should have nonzero resources
Key: MESOS-1454
URL: https://issues.apache.org/jira/browse/MESOS-1454
Project: Mesos
Issue Type: Bug
Reporter: Ian Downes
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.
