             Summary: Add default state model definitions if not already exists when controller starts
                 Key: HELIX-570
                 URL: https://issues.apache.org/jira/browse/HELIX-570
             Project: Apache Helix
          Issue Type: Bug
            Reporter: Zhen Zhang


When controller starts, we can add missing default state model definitions to the cluster. This is useful for example, the cluster is created without some new default state model definitions. Instead of building a tool to populate the new default state model definitions to existing clusters, controller can check this and add it if necessary.
