• Identify the nature of all the supported services
  • Which services are purely topology-based?
    
    • WEBHCAT
    • HBASE
    • OOZIE
    • WEBHDFS
    • ?
      
      
  • Which services are currently ZooKeeper-based?
    • HIVE (HS2ZooKeeperURLManager)
    • HBASE (HBaseZooKeeperURLManager)
    • Kafka (KafkaZooKeeperURLManager)
    • SOLR (SOLRZooKeeperURLManager)
    • ?
      
      
  • Could ZooKeeper support be added for any services which do no currently support it?
    
    
• For the ZooKeeper-based-HA services, determine if the ZooKeeper details are available from the service's configuration via Ambari.
  
  
• Determine how to leverage the cluster discovery data to generate the ZooKeeper HA configuration for the relevant declared topology services.
  
  
• Investigate moving servicecluster-specific service HA configuration from the HaProvider configuration to the service declaration.
  • This just makes more logical sense
  , and it
  • Moving cluster-specific details out of the provider configuration will make shared provider configurations applicable to more topologies (i.e., more reusable), across clusters.
  • The cluster-specific configuration could be discovered along with the service URL details, rather than having to be hard-coded.
