------------------------------------
This does not appear to prevent config changes from actually happening.
> Mpack shows UI error when changing configuration

> Key: METRON-564
> URL: https://issues.apache.org/jira/browse/METRON-564
> Project: Metron
> Issue Type: Bug
> Affects Versions: 0.2.1BETA
> Reporter: Justin Leet
> Assignee: Justin Leet
>
> 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.
