> STR:
> Install Ambari 2.4 with HDP 2.5, and attempt to add Atlas service without HBASE or LogSearch (both of which are optional).
> It calls http://server:8080/api/v1/stacks/HDP/versions/2.5/recommendations/### , which then returns the correct response with a value of "" for several Atlas configs
> "atlas.audit.hbase.zookeeper.quorum" : ""
> "atlas.graph.index.search.solr.zookeeper-url" : ""
> Both of those configs actually require a value, so if you type in any text into those textboxes and then press backspace to return to the original value of "", then the UI shows a validation error.
> I remember seeing this before, perhaps it is a regression.
> Result: missing properties for Atlas atlas.graph.index.search.solr.zookeeper-url and atlas.audit.hbase.zookeeper.quorum
