Is Ambari shows service is UP?You can look at /var/log/ranger/admin/xa_portal.log file for errors. also check whether service is listening on that port.

@Jacqualin jasmin

can you check if iptables are running in the host- you can try "service iptables stop" and then see.

You can access ranger logs in this directory :

- /opt/hadoop/log/ranger/admin

- /opt/hadoop/log/ranger/usersync

Hi ,

Thank you very much for your suggestion. Now the issue got resolved. This was related to port open issue.

@Jacqualin jasmin check that in Ambari the quick link what is the hostname it is used. If the hostname is not in your dns lookup /etc/host config in OS you might need to configure it to get the hostname resolved to correct IP and viceversa
