Hi. I read on https://cwiki.apache.org/confluence/display/solr/Setting+Up+an+External+ZooKeeper+Ensemble that Solr needs to use the same ZooKeeper version it owns (at the moment 3.4.6). Debian Jessie has ZooKeeper 3.4.5 (https://packages.debian.org/jessie/zookeeper).
Are you sure that this version won't work with Solr 5.1.0? Thank you very much for your help! Bye
