What is the best way to create TLS certificates in Cloudera Express manager for Kafka services?. I need to use JKS, but this is not available in Cloudera Express. Somehow I managed to create TLS with a self-signed certificate for Manager, but for the data nodes, I'm still struggling to create JKS. The usual method is not working for me. After the JKS certificate deployment, I restarted the Cloudera manager, I could see my Kafka is running on 9093, but I'm getting an SSL handshake when connecting to the Kafka node. What wrong I'm doing here, any leads, please? ... View more

Also, I believe truststore must have a password instead of the one I have in all clusters, don't have a password with that. How i need to work on this. I don't see any documentation for this, or I may miss landing in the correct place. I desperately need your help to get this done.  ... View more
