    'owner': 'Airflow_TEST',
    'dataflow_default_options': {
        'project':           'gcp_project',
        'region':            'us-west',
        "serviceAccount":    'my_airflow_composer.SA.com',
        "stagingLocation":   "gs://project/my_dir/staging/",
        'tempLocation':      'gs://project/my_dir/tmp/',

        'inputFilePath': "gs://project/my_dir/job/myfile.txt",
        'outputDirectory': "gs://project/my_dir/job/output"
    }
}
job_dataflow = DataflowCreateJavaJobOperator(
    gcp_conn_id='google_cloud_default',
    task_id='job_dataflow',
    jar='/tmp/lib1.jar'
    job_class='com.pipeline',
    trigger_rule='all_done',
    dag=dag
