Even with ZooKeeper, implementing coordination tasks is not trivial, but this book provides good practices to give you a head start, and points out caveats that developers and administrators alike need to watch for along the way. For that, we have created Keystore instances and added the jks files accordingly. Step 1 : Create the root CA, simply a certificate and public/private key pair, that you will use to sign the broker and client certs. Use OpenSSL to create the keystore with the service.key and service.cert files: openssl pkcs12 -export -inkey service.key -in service.cert -out client.keystore.p12 -name service_key. Operation Mode.
