Ranger WEB UI not loading.

rajatsachan — Tue, 12 Oct 2021 16:39:08 GMT

Hi all, I recently installed Ranger on Cloudera Private Cloud Base 7.1.7. Everything is installed perfectly but the ranger admin UI is not loading. The cluster is kerberized. I am able to curl the admin URL with the --negotiate flag. Is the UI not loading because of spnego authentication? If yes, how do I disable it?
We have option to disable that for HDFS and YARN, but not sure about Ranger.

Thank you!

Here is the guide to enable the SPNEGO for Browser Based interfaces.

https://docs.cloudera.com/cdp-private-cloud-base/7.1.6/security-how-to-guides/topics/cm-security-enable-web-auth-s19.html

You could try following this guide and find the option to " Enable Kerberos Authentication for HTTP Web-Consoles" in Cloudera Manager for the concerned service and then disable the ones you want.

Hope this helps.

Hi @dineshc , thank you for the suggestion but this only provides disabling HTTP authentication for HDFS, YARN and MapReduce, how can I do it for Ranger Web UI?

Or do I have a different issue altogether?

Hi @rajatsachan , While accessing the Ranger UI please try to check the Ranger admin logs. If possible please share the snippet of the error to check. It will be helpful to understand the real cause of the UI issue.

Hi @arunek95 ,

It seems the issue was with SSL and some browser configurations on Chrome. After disabling SSL, I was able to get to the UI, only on Firefox though. Clearly, this is not an installation problem or a service level issue.

Thank you for the suggestions though!
