> After some digging, it looks like the issue is that
> testRetryUpdatesWhenClusterStateIsStale implicitly relies on
> {{directUpdatesToLeadersOnly}}, and {{parallelUpdates}}, which are now
> randomized when using SolrTestCaseJ4's CloudSolrClient creation helpers.
> Attached is a patch ensuring that testRetryUpdatesWhenClusterStateIsStale
> insists on those two update-related properties, instead of taking the
> randomized defaults. Without the patch, this test passes maybe 5 out of
> twenty times. With the patch, it passes consistently (20 out of 20 runs).
