Solr webapp only reports 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 znode made available in zk >3.5. This is especially useful as zk is capable of dynamic reconfiguration.
"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
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."
