This is the documentation for CDH 5.1.x. Documentation for other versions is available at Cloudera Documentation.
Configuring Ports for CDH 5
The CDH 5 components, and third parties such as Kerberos, use the ports
listed in the tables that follow. Before you deploy CDH 5, make sure these ports are open on
each system. If you cannot follow the recommendations exactly, you must completely disable
iptables.
