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

             Summary: Utilities::isEmptyPath should throw back FNFE instead of returning true
                 Key: HIVE-21565
                 URL: https://issues.apache.org/jira/browse/HIVE-21565
             Project: Hive
          Issue Type: Bug
            Reporter: Rajesh Balamohan


In case there is a {{viewfs}} configured and it ends up throwing FNFE, current codepath silently ignores the error and ends up creating an empty file.
