> Key: SOLR-13801
> URL: https://issues.apache.org/jira/browse/SOLR-13801
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Admin UI
> Affects Versions: 7.7, 8.1, 8.2
> Reporter: Ween Jiann
> Priority: Major
>
> Solr webapp reports only a single server although solr-zookeeper-headless points to multiple zkservers. The web app can query zk for active servers which are listed in /zookeeper/config which is available in zk >3.5.
> {quote}Status: red
> Errors:
> "Leader reports 2 followers, but we only found 0. Please check zkHost configuration"; "We do not have a leader" (either one)
> ZK connection string: solr-zookeeper-headless:2181
> Ensemble size: 1
> {quote}
> Shawn has summed it up perfectly.
> "Solr should query the ZK client for information about what server hosts are active, rather than relying on the connection string, unless that information cannot be obtained by the client."
