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.
@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
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.
@Brenden Cobb no problem, I escalated your issue to get proper attention. I'm in Northeast, if you have similar issues, you can reach out to me directly. Also, please post your current status as this thread also needs to know the solution :).
