7. val PROP_BACKEND_CLUSTER_MODE: (String, String)

   

   This option can be set either to "internal" or "external" When set to "external" H2O Context is created by connecting to existing H2O cluster, otherwise it creates H2O cluster living in Spark - that means that each Spark executor will have one h2o instance running in it.

   This option can be set either to "internal" or "external" When set to "external" H2O Context is created by connecting to existing H2O cluster, otherwise it creates H2O cluster living in Spark - that means that each Spark executor will have one h2o instance running in it.
