      Description

       

       I managed to setup Zookeeper 3.5.5 with secure Client enabled and configured in solr.in.sh the zookeeper properties to use that port, which offers SSL.

      However, I see the following error in the logfiles when starting up Solr:

      Is there a jar file missing in the Solr distribution? Can this be fixed by copying the Jar file in 8.2 to the webapp/lib directory?
