Your recent update indicates that an upgrade was performed from 5.14 to 6.2.

The 500 error indicates a problem in the system response. Have you properly followed the migration and upgrade documentation found here?

https://docs.cloudera.com/documentation/enterprise/upgrade/topics/search_prepare_upgrade_cdh_6.html

[#4]

We weren't using the Solr service in the previous cluster.  So we just removed the service during the upgrade and added it after the upgrade

following the turorial we are able to create the 2 shard cores and the test collection.

Just the execute query throws exception

[#5]

We don't have any indexes or collection in this cluster.

Just trying to use it for Solr Search functions now.

We were just running the tutorial to validate the Solr service configuration.

Any steps we can take to re-initialize the service as new and get rid of any left over artifacts from the 5.14 will also be good as we don't have anything in the Search service yet.
