-----------------------------------

             Summary: WebHdfsSensor doesn't support HDFS HA
                 Key: AIRFLOW-2901
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-2901
             Project: Apache Airflow
          Issue Type: Improvement
          Components: hooks
            Reporter: Manu Zhang


If  HDFS is configured with HA, we cannot use WebHdfsSensor to check for file 
existence since WebHdfs cannot resolve the name service ID. Consider using 
[pyarrow.hdfs|https://arrow.apache.org/docs/python/filesystems.html] as a 
replacement.
