Cloudera Management Service and TLS/SSL
Configuring TLS/SSL on any server affects how clients interact with that server. For browsers, which communicate over HTTP, TLS/SSL configured on a server host redirects traffic from the HTTP port (7180) to the secure HTTP port, HTTPS (7183). When TLS Level 0 configuration is complete, the Cloudera Management Service roles are enabled for TLS encryption.
