This particular class exists as part of solr-core. does DSE-server does not have solr bundle ? (Even after placing the lib under solr lib, this particulat error occurs.
Can you please assist to resolve the issue ?
The error is most likely a symptom of another problem. For example, it's quite common to get "class not found" exceptions when using Java 11 with Cassandra. DataStax Enterprise 6.8 is compatible with Cassandra 3.11 which only supports Java 8.
For what it's worth, Java 11 support was only added to Cassandra 4.0 (CASSANDRA-16894). Older versions of Cassandra only work with Java 8.
Going back to your original question, we need a bit more information to investigate the issue but our ability to help you in a Q&A forum is limited. Please log a ticket with DataStax Support and one of our engineers will advise you on what diagnostic info is required and the next steps. Cheers!
