Methods

Modifier and Type	Method and Description
FlinkClient	getClient() Return a reference to itself.
static FlinkClient	getConfiguredClient(Map conf) Returns a FlinkClient that uses the configured Config.NIMBUS_HOST and Config.NIMBUS_THRIFT_PORT as JobManager address.
void	killTopology(String name)
void	killTopologyWithOpts(String name, backtype.storm.generated.KillOptions options)
void	submitTopology(String name, String uploadedJarLocation, FlinkTopology topology) Parameter uploadedJarLocation is actually used to point to the local jar, because Flink does not support uploading a jar file before hand.
void	submitTopologyWithOpts(String name, String uploadedJarLocation, FlinkTopology topology) Parameter uploadedJarLocation is actually used to point to the local jar, because Flink does not support uploading a jar file before hand.

public FlinkClient(Map conf,
           String host,
           int port,
           Integer timeout)

Method Detail

getConfiguredClient

public static FlinkClient getConfiguredClient(Map conf)

Returns a FlinkClient that uses the configured Config.NIMBUS_HOST and Config.NIMBUS_THRIFT_PORT as JobManager address.

Parameters:

conf - Configuration that contains the jobmanager's hostname and port.

Returns:

A configured FlinkClient.

getClient

public FlinkClient getClient()

Return a reference to itself.

FlinkClient mimics both, NimbusClient and Nimbus.Client, at once.

Returns:

A reference to itself.

submitTopology

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

Parameter uploadedJarLocation is actually used to point to the local jar, because Flink does not support uploading a jar file before hand. Jar files are always uploaded directly when a program is submitted.

Throws:

backtype.storm.generated.AlreadyAliveException

backtype.storm.generated.InvalidTopologyException

submitTopologyWithOpts

public void submitTopologyWithOpts(String name,
                          String uploadedJarLocation,
                          FlinkTopology topology)
                            throws backtype.storm.generated.AlreadyAliveException,
                                   backtype.storm.generated.InvalidTopologyException

Parameter uploadedJarLocation is actually used to point to the local jar, because Flink does not support uploading a jar file before hand. Jar files are always uploaded directly when a program is submitted.

Throws:

backtype.storm.generated.AlreadyAliveException

backtype.storm.generated.InvalidTopologyException

killTopology

public void killTopology(String name)
                  throws backtype.storm.generated.NotAliveException

Throws:

backtype.storm.generated.NotAliveException

killTopologyWithOpts

public void killTopologyWithOpts(String name,
                        backtype.storm.generated.KillOptions options)
                          throws backtype.storm.generated.NotAliveException

Throws:

backtype.storm.generated.NotAliveException
