ZooKeeper JMX port

 

9010

Internal

 

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