Examples with TestTaskBuilder org.apache.flink.runtime.taskmanager.TestTaskBuilder used on opensource projects

Example 1 with TestTaskBuilder

use of org.apache.flink.runtime.taskmanager.TestTaskBuilder in project flink by apache.

the class StreamTaskTest method taskBuilderWithConfiguredRecordWriter.

private TestTaskBuilder taskBuilderWithConfiguredRecordWriter(NettyShuffleEnvironment shuffleEnvironment) {
    Configuration taskConfiguration = new Configuration();
    outputEdgeConfiguration(taskConfiguration);
    ResultPartitionDeploymentDescriptor descriptor = new ResultPartitionDeploymentDescriptor(PartitionDescriptorBuilder.newBuilder().build(), NettyShuffleDescriptorBuilder.newBuilder().buildLocal(), 1, false);
    return new TestTaskBuilder(shuffleEnvironment).setInvokable(NoOpStreamTask.class).setTaskConfig(taskConfiguration).setResultPartitions(singletonList(descriptor));
}

Example 2 with TestTaskBuilder

use of org.apache.flink.runtime.taskmanager.TestTaskBuilder in project flink by apache.

the class StreamTaskTest method testEarlyCanceling.

/**
 * This test checks that cancel calls that are issued before the operator is instantiated still
 * lead to proper canceling.

    final StreamConfig cfg = new StreamConfig(new Configuration());

        // hit the task before the operator is deserialized
