Hi Jennifer, Take a look at index compatibility beside dependencies. Here is the explanation:
Index Format Changes Solr 6 has no support for reading Lucene/Solr 4.x and earlier indexes. Be sure to run the Lucene IndexUpgrader included with Solr 5.5 if you might still have old 4x formatted segments in your index. Alternatively: fully optimize your index with Solr 5.5 to make sure it consists only of one up-to-date index segment. You can read more from here: https://cwiki.apache.org/confluence/display/solr/Major+Changes+from+Solr+5+to+Solr+6 Kind Regards, Furkan KAMACI On Tue, Jan 3, 2017 at 7:35 PM, Jennifer Coston < jennifer.cos...@raytheon.com> wrote: > Hello, > > I am running into a conflict with Solr and ElasticSearch.
