Method Detail

createCluster

public static Cluster createCluster(java.lang.String hosts,
                                    java.lang.String ports,
                                    java.util.Map<java.lang.String,java.lang.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,
                                    java.util.Map<java.lang.String,java.lang.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:

java.lang.RuntimeException - if application properties table cannot be accessed
