[jira] [Created] (FLINK-28422) Fall back to lastest supported HiveShim when user use a higher hive version

luoyuxia created FLINK-28422:
--------------------------------

             Summary: Fall back to lastest supported HiveShim when user use a higher hive version
                 Key: FLINK-28422
                 URL: https://issues.apache.org/jira/browse/FLINK-28422
             Project: Flink
          Issue Type: Improvement
          Components: Connectors / Hive
            Reporter: luoyuxia
             Fix For: 1.16.0


Flink provides flink-connector-hive.jar, so that user can bundle it with a specific hive-exec.jar to make Flink read / write their Hive.

The flink-connector-hive mantains the Hive versions that Flink supports.  But when Hive releases a higher version, which may well be not in the maintain list of Flink for the delay of Flink's release .

Then user will find the unsupported version exception with such higher version hive-exec.jar.

The better way is to fall back to a nearest Hive version directly, with a warning message.  It usually works fine unless some big changes in Hive.
