---------------------------------------
That sounds reasonable. That way we can remove {{ZooKeeperTestEnvironment}}
entirely as part of this Jira issue. (y)
> ZooKeeperTestEnvironment does not allow for repeated test execution

> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.13.6, 1.14.3, 1.15.0
> Reporter: Matthias Pohl
> Priority: Minor
> Labels: auto-deprioritized-major, stale-minor, test-stability
>
> {{ZooKeeperTestEnvironment.deleteAll}} fails when rerunning a test due to the
> client not being started:
> {code}
> java.lang.IllegalStateException: Client is not started

> This behavior was observed when running various tests with
> repeat-until-failure enabled in Intellij:
> * {{ZooKeeperCheckpointIDCounterITCase.testShutdownRemovesState}}
> * {{ZooKeeperStateHandleStoreTest.testAddAndLock}}
> *
> {{ZooKeeperStateHandleStoreTest.testFailingAddWithPossiblyInconsistentState}}
> I'd assume that this applies in any other case as well.
