Ports Used by CDH Components
All ports listed are TCP.
In the following tables, Internal means that the port is used only for communication among the components; External means that the port can be used for either internal or external communication.

ApplicationMaster |
The ApplicationMaster serves an HTTP service using an ephemeral port that cannot be restricted. This port is never accessed directly from outside the cluster by clients. All requests to the ApplicationMaster web server is routed using the YARN ResourceManager (proxy service). Locking down access to ephemeral port ranges within the cluster's network might restrict your access to the ApplicationMaster UI and its logs, along with the ability to look at running applications. |
