Hoss Man commented on SOLR-8862:
--------------------------------
The above mentioned commit a0d48f873c21ca0ab5ba02748c1659a983aad886 on the
jira/SOLR-445 branch includes the test i was refering to.
on that branch, this seed fails100% of the time for me...

> Key: SOLR-8862
> URL: https://issues.apache.org/jira/browse/SOLR-8862
> Project: Solr
> Issue Type: Bug
> Components: Tests
> Reporter: Hoss Man
>
> I haven't been able to make sense of this yet, but what i'm seeing in a new
> SolrCloudTestCase subclass i'm writing is that the code below, which
> (reasonably) attempts to create a collection immediately after configuring
> the MiniSolrCloudCluster gets a "SolrServerException: No live SolrServers
> available to handle this request" -- in spite of the fact, that (as far as i
> can tell at first glance) MiniSolrCloudCluster's constructor is suppose to
> block until all the servers are live..
> {code}
> configureCluster(numServers)
> .addConfig(configName, configDir.toPath())
> .configure();
> Map<String, String> collectionProperties = ...;
> assertNotNull(cluster.createCollection(COLLECTION_NAME, numShards,
> repFactor,
> configName, null, null,
> collectionProperties));
> {code}
