RemoteStreamEnvironment

public RemoteStreamEnvironment(String host,
                               int port,
                               String... jarFiles)

Creates a new RemoteStreamEnvironment that points to the master (JobManager) described by the given host name and port.

Parameters:

host - The host name or address of the master (JobManager), where the program should be executed.

port - The port of the master (JobManager), where the program should be executed.

jarFiles - The JAR files with code that needs to be shipped to the cluster. If the program uses user-defined functions, user-defined input formats, or any libraries, those must be provided in the JAR files.

execute

public org.apache.flink.api.common.JobExecutionResult execute()
                                                       throws org.apache.flink.client.program.ProgramInvocationException

Description copied from class: StreamExecutionEnvironment

Triggers the program execution. The environment will execute all parts of the program that have resulted in a "sink" operation. Sink operations are for example printing results or forwarding them to a message queue.

The program execution will be logged and displayed with a generated default name.

Specified by:

execute in class StreamExecutionEnvironment

Returns:

The result of the job execution, containing elapsed time and accumulators.

Throws:

org.apache.flink.client.program.ProgramInvocationException
