             Summary: logged_in_user() UDF returns NULL value in Hive CLI and SparkSQL
                 Key: HIVE-16551
                 URL: https://issues.apache.org/jira/browse/HIVE-16551
             Project: Hive
          Issue Type: Bug
            Reporter: Matyas Orhidi


There is a recently added UDF defined in [HIVE-14100] which would return the logged in user independently of the configured authenticator, however it is not working as expected and returns NULL in HiveCLI and SparkSql on a Kerberized cluster:
