Issue while configuring TLS level 3 encryption

[#1]

Hi,

I am trying to configure the TLS level 3 encryption using method B from below link;

https://www.cloudera.com/documentation/enterprise/5-9-x/topics/cm_sg_config_tls_agent_auth.html

I alreday have a wildcard based public CA.

Question:

1] Do I need to generate the CSR request on each of the host and send the CSR to CA i.e. if I have 10 datanode then do I need to create 10 i.e. csr per node OR Since, I have the wildcard public CA, I am not required to do the same and can directly jump to "Step 5: Export the private key from the Java keystore and convert it with OpenSSL for reuse by Agent" of the documentation?

Can you please confirm the same, I would be realy thankful for the same.

Thank you,

Amit
