Review comment:
Ideally we would wait until the next checkpoint has been successfully taken.

> Run general purpose test job with failures in per-job mode
> ----------------------------------------------------------
>
> Key: FLINK-10632
> URL: https://issues.apache.org/jira/browse/FLINK-10632
> Project: Flink
> Issue Type: Sub-task
> Components: E2E Tests
> Affects Versions: 1.7.0
> Reporter: Till Rohrmann
> Assignee: Dawid Wysakowicz
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.7.0
>
>
> Similar to FLINK-8973, we should add an end-to-end which runs the general
> datastream job with failures on a per-job cluster with HA enabled (either
> directly the {{StandaloneJobClusterEntrypoint}} or a docker image based on
> this entrypoint).
> We should kill the TMs as well as the cluster entrypoint and verify that the
> job recovers.
