    :param job_name: The 'jobName' to use when executing the Dataflow job
        (templated). This ends up being set in the pipeline options, so any entry
        with key ``'jobName'`` or  ``'job_name'``in ``options`` will be overwritten.

    :param project_id: Optional, the Google Cloud project ID in which to start a job.
        If set to None or missing, the default project_id from the Google Cloud connection is used.
    :param location: Job location.
    :param gcp_conn_id: The connection ID to use connecting to Google Cloud.

    :param impersonation_chain: Optional service account to impersonate using short-term
        credentials, or chained list of accounts required to get the access_token
        of the last account in the list, which will be impersonated in the request.
        If set as a string, the account must grant the originating account
        the Service Account Token Creator IAM role.
        If set as a sequence, the identities from the list must grant
        Service Account Token Creator IAM role to the directly preceding identity, with first
        account from the list granting this role to the originating account (templated).

            This option requires Apache Beam 2.39.0 or newer.

    :param drain_pipeline: Optional, set to True if want to stop streaming job by draining it
        instead of canceling during killing task instance. See:
        https://cloud.google.com/dataflow/docs/guides/stopping-a-pipeline
    :param cancel_timeout: How long (in seconds) operator should wait for the pipeline to be
        successfully cancelled when task is being killed. (optional) default to 300s
    :param wait_until_finished: (Optional)
        If True, wait for the end of pipeline execution before exiting.
        If False, only submits job.
        If None, default behavior.

        The default behavior depends on the type of pipeline:

        * for the streaming pipeline, wait for jobs to start,
        * for the batch pipeline, wait for the jobs to complete.

        .. warning::
            You cannot call ``PipelineResult.wait_until_finish`` method in your pipeline code for the operator
            to work properly. i. e. you must use asynchronous execution. Otherwise, your pipeline will
            always wait until finished. For more information, look at:
            `Asynchronous execution
            <https://cloud.google.com/dataflow/docs/guides/specifying-exec-params#python_10>`__

        The process of starting the Dataflow job in Airflow consists of two steps:
        * running a subprocess and reading the stderr/stderr log for the job id.
        * loop waiting for the end of the job ID from the previous step by checking its status.

        Step two is started just after step one has finished, so if you have wait_until_finished in your
        pipeline code, step two will not start until the process stops. When this process stops,
        steps two will run, but it will only execute one iteration as the job will be in a terminal state.

        If you in your pipeline do not call the wait_for_pipeline method but pass wait_until_finish=True
        to the operator, the second loop will wait for the job's terminal state.

        If you in your pipeline do not call the wait_for_pipeline method, and pass wait_until_finish=False
        to the operator, the second loop will check once is job not in terminal state and exit the loop.
    :param multiple_jobs: If pipeline creates multiple jobs then monitor all jobs. Supported only by
        :class:`~airflow.providers.apache.beam.operators.beam.BeamRunJavaPipelineOperator`.

          If the value is ``['A', 'B']`` and the key is ``key`` then the ``--key=A --key=B`` options
          will be left
        * Other value types will be replaced with the Python textual representation.

        When defining labels (``labels`` option), you can also provide a dictionary.

    :param project_id: Optional, the Google Cloud project ID in which to start a job.
        If set to None or missing, the default project_id from the Google Cloud connection is used.

        is often not the main class configured in the dataflow jar file.

    Note that both
    ``dataflow_default_options`` and ``options`` will be merged to specify pipeline
    execution parameter, and ``dataflow_default_options`` is expected to save
    high-level options, for instances, project and zone information, which
    apply to all dataflow operators in the DAG.

    It's a good practice to define dataflow_* parameters in the default_args of the dag
    like the project, zone and staging location.

    .. code-block:: python

       default_args = {
           "dataflow_default_options": {
               "zone": "europe-west1-d",
               "stagingLocation": "gs://my-staging-bucket/staging/",
           }
       }

    You need to pass the path to your dataflow as a file reference with the ``jar``
    parameter, the jar needs to be a self executing jar (see documentation here:
    https://beam.apache.org/documentation/runners/dataflow/#self-executing-jar).
    Use ``options`` to pass on options to your job.

    :param cancel_timeout: How long (in seconds) operator should wait for the pipeline to be
        successfully cancelled when task is being killed.
    :param append_job_name: True if unique suffix has to be appended to job name.
    :param wait_until_finished: (Optional)
        If True, wait for the end of pipeline execution before exiting.
        If False, only submits job.
        If None, default behavior.

        The default behavior depends on the type of pipeline:

        * for the streaming pipeline, wait for jobs to start,
        * for the batch pipeline, wait for the jobs to complete.

        .. warning::

            You cannot call ``PipelineResult.wait_until_finish`` method in your pipeline code for the operator
            to work properly. i. e. you must use asynchronous execution. Otherwise, your pipeline will
            always wait until finished. For more information, look at:
            `Asynchronous execution
            <https://cloud.google.com/dataflow/docs/guides/specifying-exec-params#python_10>`__

        The process of starting the Dataflow job in Airflow consists of two steps:

        * running a subprocess and reading the stderr/stderr log for the job id.
        * loop waiting for the end of the job ID from the previous step.
          This loop checks the status of the job.

        Step two is started just after step one has finished, so if you have wait_until_finished in your
        pipeline code, step two will not start until the process stops. When this process stops,
        steps two will run, but it will only execute one iteration as the job will be in a terminal state.

        If you in your pipeline do not call the wait_for_pipeline method but pass wait_until_finish=True
        to the operator, the second loop will wait for the job's terminal state.

        If you in your pipeline do not call the wait_for_pipeline method, and pass wait_until_finish=False
        to the operator, the second loop will check once is job not in terminal state and exit the loop.

    It's a good practice to define dataflow_* parameters in the default_args of the dag
    like the project, zone and staging location.

    .. seealso::
        https://cloud.google.com/dataflow/docs/reference/rest/v1b3/LaunchTemplateParameters
        https://cloud.google.com/dataflow/docs/reference/rest/v1b3/RuntimeEnvironment

    .. code-block:: python

       default_args = {
           "dataflow_default_options": {
               "zone": "europe-west1-d",
               "tempLocation": "gs://my-staging-bucket/staging/",
           }
       }

    You need to pass the path to your dataflow template as a file reference with the
    ``template`` parameter. Use ``parameters`` to pass on parameters to your job.
    Use ``environment`` to pass on runtime environment variables to your job.

    .. code-block:: python

       t1 = DataflowTemplatedJobStartOperator(
           task_id="dataflow_example",
           template="{{var.value.gcp_dataflow_base}}",
           parameters={
               "inputFile": "gs://bucket/input/my_input.txt",
               "outputFile": "gs://bucket/output/my_output.txt",
           },
           gcp_conn_id="airflow-conn-id",
           dag=my_dag,
       )

    ``template``, ``dataflow_default_options``, ``parameters``, and ``job_name`` are
    templated, so you can use variables in them.

    Note that ``dataflow_default_options`` is expected to save high-level options
    for project information, which apply to all dataflow operators in the DAG.

class DataflowCreatePythonJobOperator(GoogleCloudBaseOperator):
    """
    Launching Cloud Dataflow jobs written in python.

    Note that both dataflow_default_options and options will be merged to specify pipeline
    execution parameter, and dataflow_default_options is expected to save high-level options,
    for instances, project and zone information, which apply to all dataflow operators in the DAG.

    This class is deprecated.

    Please use :class:`providers.apache.beam.operators.beam.BeamRunPythonPipelineOperator`.

    .. seealso::
        For more detail on job submission have a look at the reference:
        https://cloud.google.com/dataflow/pipelines/specifying-exec-params

    .. seealso::
        For more information on how to use this operator, take a look at the guide:
        :ref:`howto/operator:DataflowCreatePythonJobOperator`

    :param py_file: Reference to the python dataflow pipeline file.py, e.g.,
        /some/local/file/path/to/your/python/pipeline/file. (templated)
    :param job_name: The 'job_name' to use when executing the Dataflow job
        (templated). This ends up being set in the pipeline options, so any entry
        with key ``'jobName'`` or ``'job_name'`` in ``options`` will be overwritten.
    :param py_options: Additional python options, e.g., ["-m", "-v"].
    :param dataflow_default_options: Map of default job options.
    :param options: Map of job specific options.The key must be a dictionary.
        The value can contain different types:

        * If the value is None, the single option - ``--key`` (without value) will be added.
        * If the value is False, this option will be skipped
        * If the value is True, the single option - ``--key`` (without value) will be added.
        * If the value is list, the many options will be added for each key.
          If the value is ``['A', 'B']`` and the key is ``key`` then the ``--key=A --key=B`` options
          will be left
        * Other value types will be replaced with the Python textual representation.

        When defining labels (``labels`` option), you can also provide a dictionary.
    :param py_interpreter: Python version of the beam pipeline.
        If None, this defaults to the python3.
        To track python versions supported by beam and related
        issues check: https://issues.apache.org/jira/browse/BEAM-1251
    :param py_requirements: Additional python package(s) to install.
        If a value is passed to this parameter, a new virtual environment has been created with
        additional packages installed.

        You could also install the apache_beam package if it is not installed on your system or you want
        to use a different version.
    :param py_system_site_packages: Whether to include system_site_packages in your virtualenv.
        See virtualenv documentation for more information.

        This option is only relevant if the ``py_requirements`` parameter is not None.
    :param gcp_conn_id: The connection ID to use connecting to Google Cloud.
    :param project_id: Optional, the Google Cloud project ID in which to start a job.
        If set to None or missing, the default project_id from the Google Cloud connection is used.
    :param location: Job location.
    :param poll_sleep: The time in seconds to sleep between polling Google
        Cloud Platform for the dataflow job status while the job is in the
        JOB_STATE_RUNNING state.
    :param drain_pipeline: Optional, set to True if want to stop streaming job by draining it
        instead of canceling during killing task instance. See:
        https://cloud.google.com/dataflow/docs/guides/stopping-a-pipeline
    :param cancel_timeout: How long (in seconds) operator should wait for the pipeline to be
        successfully cancelled when task is being killed.
    :param wait_until_finished: (Optional)
        If True, wait for the end of pipeline execution before exiting.
        If False, only submits job.
        If None, default behavior.

        The default behavior depends on the type of pipeline:

        * for the streaming pipeline, wait for jobs to start,
        * for the batch pipeline, wait for the jobs to complete.

        .. warning::

            You cannot call ``PipelineResult.wait_until_finish`` method in your pipeline code for the operator
            to work properly. i. e. you must use asynchronous execution. Otherwise, your pipeline will
            always wait until finished. For more information, look at:
            `Asynchronous execution
            <https://cloud.google.com/dataflow/docs/guides/specifying-exec-params#python_10>`__

        The process of starting the Dataflow job in Airflow consists of two steps:

        * running a subprocess and reading the stderr/stderr log for the job id.
        * loop waiting for the end of the job ID from the previous step.
          This loop checks the status of the job.

        Step two is started just after step one has finished, so if you have wait_until_finished in your
        pipeline code, step two will not start until the process stops. When this process stops,
        steps two will run, but it will only execute one iteration as the job will be in a terminal state.

        If you in your pipeline do not call the wait_for_pipeline method but pass wait_until_finish=True
        to the operator, the second loop will wait for the job's terminal state.

        If you in your pipeline do not call the wait_for_pipeline method, and pass wait_until_finish=False
        to the operator, the second loop will check once is job not in terminal state and exit the loop.
