Method Detail

execute

public org.apache.flink.api.common.JobExecutionResult execute()
                                                       throws Exception

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.

Overrides:

execute in class StreamExecutionEnvironment

Returns:

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

Throws:

Exception - which occurs during job execution.
