------------------------------------

This does not appear to prevent config changes from actually happening.

> When confirming configuration changes, the Ambari UI shows an error that it cannot validate configuration consistency.
> An error in the logs refers to the service advisor (getServiceConfigurationRecommendations), in particular a method that actually appears twice in the file, which is probably the root cause. This first instance of this method should be removed, and the error fixed.
