By default the Cloudera Manager Web UI listens on port 7180.
If our environment or company policy requires Cloudera Manager to use a different port, how can I change it?
Modify the Cloudera Manager HTTP Port
Create an SSH Tunnel to Cloudera Manager
$ ssh -L 9999:localhost:7180 email@example.com
3. Once you are logged on, visit http://locahost:9999/ on your local browser and it will pipe traffic to/from cmbox.example.com:7180
Note: While the change can also be completed via direct database manipulation it is error-prone and tedious, therefore it is not a recommended method.
