1. Can you please share the exact set of tags where you made the port changes inside the "server.xml"

2. On the tomcat host are you able to see the port is listening and bound properly?

# netstat -tnlpa | grep 12123
# netstat -tnlpa | grep 2222

3. Do you see any error inside the "catalina.out" ?

4. Is there any restriction at firewall level which is restricting the port 12123 access? Can you check the firewall rules (may be it is set in such a way that the port 2222 only will be accessible).

Hi,

1. Attaching you the server.xml

2. netstat -tnlpa | grep 12123 .

below is the output .

tcp 0 0 :::12123 :::* LISTEN 10595/java

netstat -tnlpa | grep 2222

The above command gives no output.

3. Catalina.out has no error.

4.How to check firewall ? Also

this url is working fine

http://52.177.199.181:8888/splash2.html.

http://52.177.199.181:8080/ is not displaying anything . I guess there is firewall issue.

Are you talking about Azure HDP Sandbox?

If yes, then there is a separate way to add ports. As it runs on docker container. Please see the following guides to know how sandbox exposes the ports.

Add ports to Azure HDP Sandbox Docker: https://hortonworks.com/tutorial/sandbox-port-forwarding-guide/section/4/

For adding new Ports: https://community.hortonworks.com/articles/65914/how-to-add-ports-to-the-hdp-25-virtualbox-sandbox.html (even though this link says VirtualBox but should be fine in your case)

The prerequisite of setting up the Azure Sandbox is described here: https://hortonworks.com/tutorial/sandbox-deployment-and-install-guide/section/4/

So please check if you have done the Local Forwards properly or not as described in the above link?

Please try this.

Change your Tomcat port to 9090 (instead of 2222) and then try again

9090 is the defauilt Nifi Port , which might not be running on your Sandbox and the port forwarding rules are already setup for port 9090 so you should be fine with this port.

Change the tomcat port to 9090 and then restart the tomcat then try accessing the tomcat URL on this port.

Thanks for the help.
