Examples with PipelineExecutorFactory org.apache.flink.core.execution.PipelineExecutorFactory used on opensource projects

Example 1 with PipelineExecutorFactory

use of org.apache.flink.core.execution.PipelineExecutorFactory in project flink by apache.

the class ExecutionEnvironment method executeAsync.

/**
 * 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 ({@link DataSet#print()}, writing results (e.g. {@link DataSet#writeAsText(String)},
 * {@link DataSet#write(org.apache.flink.api.common.io.FileOutputFormat, String)}, or other
 * generic data sinks created with {@link
 * DataSet#output(org.apache.flink.api.common.io.OutputFormat)}.
 *
 * <p>The program execution will be logged and displayed with the given job name.
 *
 * @return A {@link JobClient} that can be used to communicate with the submitted job, completed
 *     on submission succeeded.
 * @throws Exception Thrown, if the program submission fails.

use of org.apache.flink.core.execution.PipelineExecutorFactory in project flink by apache.

the class StreamExecutionEnvironment method executeAsync.

/**
