Description

While installing a fresh cluster, a config group got created "accidentally" but no hosts were associated with it.
So, create the config group and save it but do not associate any hosts.

If you proceed, the install/start phase fails with the following:

org.apache.ambari.server.controller.spi.SystemException: An internal system exception occurred: Config group not found, clusterName = c1, groupId = 1472253656242

Error in ambari server log:
