    • createCluster

      public static Cluster createCluster(String hosts, String ports, Map<String,String> options)
      Convenience method for creating a metadata cluster. This method creates the BridgeServer objects that define the cluster.
      Parameters:
      hosts - space delimited list of host names. May be abbreviated to a single name if the same host is used for all cluster nodes. May be null or empty if cluster properties lookup is enabled.
      ports - space delimited list of port numbers. May be abbreviated to a single port if the same port is used for all cluster nodes. May be null or empty if cluster properties lookup is enabled.
      options - connection options. See OPTION_* constants for available options.
      Returns:
      cluster definition

    • createCluster

      public static Cluster createCluster(HostPortSet clusterNodes, Map<String,String> options)
      Convenience method for creating a metadata cluster. This method creates the BridgeServer objects that define the cluster.
      Parameters:
      clusterNodes - one or more nodes making up the cluster. May be null or empty if and only if the sas.metadata.use.cluster.properties system property or OPTION_USE_CLUSTER_PROPERTIES option is true.
      options - connection options. See OPTION_* constants for available options.
      Returns:
      cluster definition

    • getClusterHostPortSet

      public static HostPortSet getClusterHostPortSet()
      Returns host/port collection for metadata server cluster as defined in the application properties table. Returns null if sas.metadata.use.cluster.properties system property is not defined.
      Returns:
      host/port collection for metadata server cluster as defined in the application properties table
      Throws:
      RuntimeException - if application properties table cannot be accessed
