lirui-apache commented on issue #8859: [FLINK-12905][table-planner] Enable querying CatalogViews in legacy planner URL: https://github.com/apache/flink/pull/8859#issuecomment-505697061 For Hive to access (non-generic) views created by Flink, we need to 1) remove the catalog part from the object paths and 2) make sure the expanded query is valid HiveQL syntax. To achieve the above in Blink, we used Hive's analyzer to analyze the original query in order to get a Hive-compatible expanded query. Blink's expanded query is stored as a property of the view, and will be restored if the view is accessed from Blink side. If we're to do the same in Flink, I guess it can be done in a separate PR. And the prerequisite is that `CatalogView` preserves the original query when it reaches `HiveCatalog::createTable`.
