I had to restore an Ambari database backup, which was a bit behind the current cluster status. Will the Ambari restore "rollback" config changes upon cluster startup, and if so is there a way to "refresh" Ambari with what's current in the cluster. Thank you.

Thank you both for your help. Support case was escalated and received excellent guidance for getting Ambari back in sync. The primary resolution for the sync issue raised here was executing $ ambari-server upgradestack HDP-2.3

@Brenden Cobb Are you upgrading ambari? Whats the previous and latest version?
2.3.2 is HDP version
2.2.0 is Ambari version

Nope, not upgrading anything. Ambari database stack options:
select * from stack; stack_id | stack_name | stack_version ----------+------------+----------------- 1 | HDP | 2.3 2 | HDP | 2.1.GlusterFS 3 | HDP | 2.2 4 | HDP | 2.1 5 | HDP | 2.0 6 | HDP | 2.0.6 7 | HDP | 2.3.GlusterFS 8 | HDP | 2.0.6.GlusterFS

Also:
$ ls /usr/hdp 2.2.0.0-2041 2.2.4.2-2 2.3.2.0-2950 current
Where current is correctly pointing to 2.3.x

@Brenden Cobb Are you doing this in production? We need to escalate this as p1 case so that someone from support can help you. HDP 2.2 vs. 2.3 under current...This is not good

since this is after-effect, I'd open a ticket with support. In my experience, i would backup all configs on every node, then try to restart agent on one node at a time as agent will advertise current config on a node to ambari server. Once you confirm everything is restored for that node, you can go to next node.

Thanks I will keep that in mind as I progress. Support is not very helpful at the moment..that's why dropped by.

@Brenden Cobb which region are you in? You can tail the Ambari server log for configbstatus. @Mark Herring
