---------------------------------
Assignee: Greg Mann
> Agent incorrectly handles draining when empty
> ---------------------------------------------
>
> Key: MESOS-10118
> URL: https://issues.apache.org/jira/browse/MESOS-10118
> Project: Mesos
> Issue Type: Bug
> Components: agent
> Affects Versions: 1.9.0
> Reporter: Greg Mann
> Assignee: Greg Mann
> Priority: Major
>
> When the agent receives a {{DrainSlaveMessage}} and does not have any tasks
> or operations, it writes the {{DrainConfig}} to disk and is then implicitly
> stuck in a "draining" state indefinitely. For example, if an agent
> reregistration is triggered at such a time, the master may think the agent is
> operating normally and send a task to it, at which point the task will fail
> because the agent thinks it's draining (see this test for an example:
> https://reviews.apache.org/r/72364/).
> If the agent receives a {{DrainSlaveMessage}} when it has no tasks or
> operations, it should avoid writing any {{DrainConfig}} to disk so that it
> immediately "transitions" into the already-drained state.
