Steve Rowe commented on SOLR-10916:
-----------------------------------
{{TestCollectionsAPIViaSolrCloudCluster.testCollectionCreateSearchDelete()}}
has been failing pretty regularly (11 out of 100 iterations when I beasted it
on master just now). The problem: a doc addition fails after intentionally
killing a couple of solr's jetties, apparently because the client attempts to
send an update to a shard that isn't there. I'm beasting a change that calls
{{client.getZkStateReader().forceUpdateCollection()}} before adding the doc,
but it seems like CloudSolrClient ought to be able to detect this problem and
retry after refreshing the cluster state?

> We have a non-trivial number of tests that extend LuceneTestCase directly.
> For "utility" method minded tests, this is fine - but for any test that wants
> to instantiate re-use shared config files to instantiate SolrCores, or
> instances of MiniSolrCloudCluster, this makes these tests really cumbersome
> to maintain and deal with because htye don't leverage the existing
> randomization setup logic in SolrTestCaseJ4.
> we should fix these tests where applicable
