after decommissioning nodes (delete host), we see new conf created which are identical to old conf

Ambari 1.7, after decommissioning nodes (delete host), we see new version of conf created to HDFS, Yarn, HBase, Hive... but they are identical to previous conf.

Is it a known issue? can we make the previous version as current to avoid "restart required labels"?

@rxu Ambari conf can be identical but node list is changed, meaning a decommissioned node is purged from list of known hosts. Going back to previous configs will not solve your problem of stale configs, you will still need to restart services. Try to restart services per node rather than per service and you'll be able to get through it. This is not an issue, it's by design.

We set the previous version of conf as current, and it works.
