> Key: AIRFLOW-2773
> URL: https://issues.apache.org/jira/browse/AIRFLOW-2773
> Project: Apache Airflow
> Issue Type: Bug
> Components: Dataflow
> Affects Versions: 1.9.0
> Reporter: Evgeny Podlepaev
> Assignee: Kaxil Naik
> Priority: Minor
> Fix For: 2.0.0
>
>
> DataFlowPythonOperator generates a job name that does not get accepted by
> Dataflow API when task_id contains underscores. Example:
> DataFlowPythonOperator(task_id='analyze_search_results', ...)
> will lead to the following error:
> ValueError: Pipeline has validations errors: Invalid job_name
> (analyze_search_results-02e17268); the name must consist of only the
> characters [-a-z0-9], starting with a letter and ending with a letter or
> number.
> The fix seems to be as simple as changing
> DataFlowHook.start_python_dataflow() to do
> name = task_id.replace('_', '-')
