> Jepsen: runit supervised sshd is stopped on tear down
> -----------------------------------------------------
>
> Key: FLINK-10465
> URL: https://issues.apache.org/jira/browse/FLINK-10465
> Project: Flink
> Issue Type: Bug
> Components: Tests
> Affects Versions: 1.7.0, 1.6.2
> Reporter: Gary Yao
> Assignee: Gary Yao
> Priority: Critical
> Labels: pull-request-available
> Fix For: 1.7.0, 1.6.2
>
>
> When tearing down the _DB_, we tear down all services supervised by runit.
> However when running the tests in Docker, sshd is under supervision by runit.
> When sshd is stopped, the tests cannot be continued because the control node
> cannot interact with the DB nodes anymore.
> *How to reproduce*
> Run command below in control-node container:
> {code}
> ./docker/run-tests.sh 1
> [...]/flink/flink-1.6.1/flink-1.6.1-bin-hadoop28-scala_2.11.tgz
> {code}
> *Expected behavior*
> sshd should never be stopped
