[ https://issues.apache.org/jira/browse/SOLR-8599?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Keith Laban updated SOLR-8599: -- Attachment: SOLR-8599.patch uploaded a new patch against master addressing Uwes concerns. I see that this was already merged in master, but that seems to be the only branch its currently on so hopefully its ok to put this out there. Instead of scheduling a thread to change the address I was able to mock the DefaultConnectionStrategy to throw an exception in the reconnect call the first time its called to verify that it is being retried. With this change I also changed the server address to be final again and removed the public setter method seeing how they were no longer needed > Errors in construction of SolrZooKeeper cause Solr to go into an inconsistent > state > --- > > Key: SOLR-8599 > URL: https://issues.apache.org/jira/browse/SOLR-8599 > Project: Solr > Issue Type: Bug > Components: SolrCloud >Reporter: Keith Laban >Assignee: Dennis Gove > Attachments: SOLR-8599.patch, SOLR-8599.patch, SOLR-8599.patch, > SOLR-8599.patch > > > We originally saw this happen due to a DNS exception (see stack trace below). > Although any exception thrown in the constructor of SolrZooKeeper or the > parent class, ZooKeeper, will cause DefaultConnectionStrategy to fail to > update the zookeeper client.
