Method Detail

submitTopology

public static void submitTopology(String name,
                  Map<?,?> stormConf,
                  FlinkTopology topology,
                  backtype.storm.generated.SubmitOptions opts)
                           throws backtype.storm.generated.AlreadyAliveException,
                                  backtype.storm.generated.InvalidTopologyException

Submits a topology to run on the cluster. A topology runs forever or until explicitly killed.

Parameters:

name - the name of the storm.

stormConf - the topology-specific configuration. See Config.

topology - the processing to execute.

opts - to manipulate the starting of the topology.

Throws:

backtype.storm.generated.AlreadyAliveException - if a topology with this name is already running

backtype.storm.generated.InvalidTopologyException - if an invalid topology was submitted

submitTopology

public static void submitTopology(String name,
                  Map stormConf,
                  FlinkTopology topology)
                           throws backtype.storm.generated.AlreadyAliveException,
                                  backtype.storm.generated.InvalidTopologyException

Submits a topology to run on the cluster. A topology runs forever or until explicitly killed. The given FlinkSubmitter.FlinkProgressListener is ignored because progress bars are not supported by Flink.

Parameters:

name - the name of the storm.

stormConf - the topology-specific configuration. See Config.

topology - the processing to execute.

Throws:

backtype.storm.generated.AlreadyAliveException - if a topology with this name is already running

backtype.storm.generated.InvalidTopologyException - if an invalid topology was submitted

submitTopologyWithProgressBar

public static void submitTopologyWithProgressBar(String name,
                                 Map<?,?> stormConf,
                                 FlinkTopology topology)
                                          throws backtype.storm.generated.AlreadyAliveException,
                                                 backtype.storm.generated.InvalidTopologyException

Same as submitTopology(String, Map, FlinkTopology, SubmitOptions). Progress bars are not supported by Flink.

Parameters:

name - the name of the storm.

stormConf - the topology-specific configuration. See Config.

topology - the processing to execute.

Throws:

backtype.storm.generated.AlreadyAliveException - if a topology with this name is already running

backtype.storm.generated.InvalidTopologyException - if an invalid topology was submitted

submitJar

public static String submitJar(Map conf,
               String localJar)

In Flink, jar files are submitted directly when a program is started. Thus, this method does nothing. The returned value is parameter localJar, because this give the best integration of Storm behavior within a Flink environment.

Parameters:

conf - the topology-specific configuration. See Config.

localJar - file path of the jar file to submit

Returns:

the value of parameter localJar

submitJar

public static String submitJar(String localJar)

In Flink, jar files are submitted directly when a program is started. Thus, this method does nothing. The returned value is parameter localJar, because this give the best integration of Storm behavior within a Flink environment.

Parameters:

localJar - file path of the jar file to submit

Returns:

the value of parameter localJar
