> Jepsen: Kill Flink processes when tearing down cluster
> ------------------------------------------------------
>
> Key: FLINK-9949
> URL: https://issues.apache.org/jira/browse/FLINK-9949
> Project: Flink
> Issue Type: Bug
> Components: Tests
> Affects Versions: 1.6.0
> Reporter: Gary Yao
> Assignee: Gary Yao
> Priority: Critical
> Labels: pull-request-available
> Fix For: 1.6.0
>
>
> Because Flink processes are not killed at the end of the tests, it can happen
> that surviving instances create znodes in the ZooKeeper ensemble of the next
> test run. This creates ambiguity when we retrieve the address of the leading
> REST server from ZooKeeper.
