In the past, if Select returned no rows, hadoop would still create an empty file. Some customer would use this file to help with their work flow. In https://issues.apache.org/jira/browse/HIVE-13040 this was fixed, because anyone using cloud based solutions could be charged for empty files, so it was determined that hadoop should not write the files.
