ApplicationMaster

    

External

  

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.

ZooKeeper JMX port

 

9010

Internal

 
ZooKeeper will also use another randomly selected port for RMI. To allow Cloudera Manager to monitor ZooKeeper, you must do one of the following:
  • Open up all ports when the connection originates from the Cloudera Manager Server
  • Do the following:
    1. Open a non-ephemeral port (such as 9011) in the firewall.
    2. Install Oracle Java 7u4 JDK or higher.
    3. Add the port configuration to the advanced configuration snippet, for example: 
      -Dcom.sun.management.
jmxremote.rmi.port=9011
    4. Restart ZooKeeper.
