James Peach commented on MESOS-8585:
------------------------------------
Yeh, crashing in this case seems pretty unfortunate. Probably
`createExecutorDirectory` should return an error and we should refactor the
callers to be able to propagate that correctly.
> Agent Crashes When Ask to Start Task with Unknown User

> Key: MESOS-8585
> URL: https://issues.apache.org/jira/browse/MESOS-8585
> Project: Mesos
> Issue Type: Bug
> Components: agent
> Affects Versions: 1.5.0
> Reporter: Karsten
> Priority: Major
> Attachments: dcos-mesos-slave.service.1.gz,
> dcos-mesos-slave.service.2.gz
>
>
> The Marathon team has an integration test that tries to start a task with an
> unknown user. The test expects a \{{TASK_FAILED}}. However, we see
> \{{TASK_DROPPED}} instead. The agent logs seem to suggest that the agent
> crashes and restarts.
