Description

In HDP 2.5, cannot enable Atlas Server HA because the cardinality is set to 1 instead of 1+

http://server:8080/api/v1/stacks/HDP/versions/2.5/services/ATLAS/components/ATLAS_SERVER

cardinality: "1"

Looks like a copy-paste error while committing on behalf of another dev,

ambari-server/src/main/resources/stacks/HDP/2.5/services/ATLAS/metainfo.xml

Workaround:
Edit /var/lib/ambari-server/resources/stacks/HDP/2.5/services/ATLAS/metainfo.xml and change cardinality of Atlas Server from "1" to "1+" and restart Ambari Server
