Ambari usage and tweaking

Changing the default web port

By default, the Ambari web GUI is listening on port 8080. It is really easy to change this port.
On the command line of your Ambari Server, you will just do that:
  1. Stop the Ambari server ( sudo ambari-server stop )
  2. Edit the file /etc/ambari-server/conf/
  3. Add the line client.api.port=<your port>
