Method Detail

executeAsync

public JobClient executeAsync(String jobName)
                       throws Exception

Description copied from class: ExecutionEnvironment

Triggers the program execution asynchronously. The environment will execute all parts of the program that have resulted in a "sink" operation. Sink operations are for example printing results (DataSet.print(), writing results (e.g. DataSet.writeAsText(String), DataSet.write(org.apache.flink.api.common.io.FileOutputFormat, String), or other generic data sinks created with DataSet.output(org.apache.flink.api.common.io.OutputFormat).

The program execution will be logged and displayed with the given job name.

Overrides:

executeAsync in class ExecutionEnvironment

Returns:

A JobClient that can be used to communicate with the submitted job, completed on submission succeeded.

Throws:

Exception - Thrown, if the program submission fails.
