Dmytro Grinenko commented on AMBARI-25591:
------------------------------------------
[~dhire...@gmail.com] while RCA is not used anymore, it still marked as
"[deprecated|https://github.com/apache/ambari/blob/branch-2.7/ambari-server/src/main/java/org/apache/ambari/server/configuration/Configuration.java#L1354]";
and should be set properly. The default value is "mapred" through.
In current state settings for default connection and RCA should match and with
embedded mode, setup script will configure both properties properly.
