[jira] [Resolved] (KAFKA-1869) Openning some random ports while
running kafka service
[ https://issues.apache.org/jira/browse/KAFKA-1869?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Manikumar Reddy resolved KAFKA-1869.
------------------------------------
Resolution: Not a Problem
Fix Version/s: 0.8.2
Assignee: Manikumar Reddy
These ports are JMX related ports. One port is com.sun.management.jmxremote.rmi.port and another port is for the JMX RMI registry of the local only server. These ports are for local use and will not create any problem.
