[jira] [Updated] (AIRFLOW-2901) WebHdfsSensor doesn't support HDFS HA

     [ https://issues.apache.org/jira/browse/AIRFLOW-2901?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Manu Zhang updated AIRFLOW-2901:
--------------------------------
    Description: 
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.

An alternative way is to allow users to configure a list of namenodes if the dependencies of pyarrow (including libhdfs.so) are too heavy
