[jira] [Created] (FLINK-17922) Refactor generic and hive table rules for HiveCatalog

[Shang Yuanchun (Jira)]

Jingsong Lee created FLINK-17922:
------------------------------------

             Summary: Refactor generic and hive table rules for HiveCatalog
                 Key: FLINK-17922
                 URL: https://issues.apache.org/jira/browse/FLINK-17922
             Project: Flink
          Issue Type: Bug
          Components: Connectors / Hive
            Reporter: Jingsong Lee
             Fix For: 1.12.0


Now the underlying rules are:
 * HiveCatalog.createTable , hive table has false of {{isGeneric}} flag, generic table has no flag.
 * HiveCatalog.getTable , generic table has true of {{isGeneric}} flag, hive table has no flag.

It is very difficult to understand and easy to cause bugs.

Whether it's {{createTable}} or {{getTable}} of {{HiveCatalog}}, there should be two types of objects that are consistent: {{HiveCatalogTable}} and Flink {{CatalogTableImpl}}.

Timo: From a logical perspective, the {{HiveCatalog}} should deal with this additional property while storing and retrieving a {{CatalogTable}}. The {{isGeneric}} should not travel through the stack of regular Flink connector options. It is an internal property from the {{HiveCatalog}} through a custom {{HiveCatalogTable}} to a custom {{HiveFactory}}. It should be stored as a member variable in a {{HiveCatalogTable}}.
