HDP Upgrade - Pre-Upgrade checks failed from 2.6.3 to 3.1.0

[#1]

Hi,

We are in the process of upgrading the HDP stack from 2.6.3 to 3.1.0 and we face the following error.

 Verify Ambari and Ranger Password Synchronization Reason: Credentials for user 'amb_ranger_admin' in Ambari do not match Ranger.Failed on: RANGER

We did change the password in Ranger and followed by the Ambari as well. Not sure why this synchronization is not happening?

Can any one help me out on this.

Thanks!

Check is "amb_ranger_admin" user is internal or external user, if it is external user then delete that user and create it as internal user and set the password for same, and update Ranger configs in Ambari UI with new password for "Ranger Admin user's password for Ambari

I just changed the amb_ranger_admin password along with the admin password in the Ranger UI and in the ambari for ranger admin then it started working. Thanks!
