Subject Re: Why Doesn't Solr Really Quit on Zookeeper Exceptions?
Date Tue, 31 May 2016 21:57:18 GMT
The retry logic for errors in construction of SolrZooKeeper was added in
https://issues.apache.org/jira/browse/SOLR-8599 and is in 5.5.1 and 6.0. I
wonder if either that is not working as expected during startup or if
startup is following a different code path.
