Configuring Ports for Cloudera Manager
Cloudera Manager, CDH components, managed services, and third-party components use the ports listed in the tables that follow. Before you deploy Cloudera Manager, CDH, and managed services, and third-party components make sure these ports are open on each system. If you are using a firewall, such as iptables, and cannot open all the listed ports, you will need to disable the firewall completely to ensure full functionality.
