The Spark UI uses the TLS certificates from your cassandra.yaml client_encryption_options parameter.

Please post your client encryption options from cassandra.yaml.

In DSE, the Spark UI inherits the client encryption options configured in cassandra.yaml by default with this configuration in dse.yaml:

spark_ui_options:
    encryption: inherit

If you have not enabled client encryption for your cluster, you can secure the Spark UI independently by setting the encryption option to custom:

spark_ui_options:
    encryption: custom

and configure the TLS certificate. See step 3 of Securing Spark connections in DSE for details.
