anchovYu opened a new pull request, #44328: URL: https://github.com/apache/spark/pull/44328
### What changes were proposed in this pull request? When the SQL conf `spark.sql.legacy.keepCommandOutputSchema` is set to true: Before: ``` // support there is a xyyu-db-with-hyphen schema in the catalog spark.catalog.listDatabases() [INVALID_IDENTIFIER] The identifier xyyu-db-with-hyphen is invalid. Please, consider quoting it with back-quotes as `xyyu-db-with-hyphen`. SQLSTATE: 42602 (line 1, pos 4) ``` After: ``` spark.catalog.listDatabases() .. `xyyu-db-with-hyphen` .. ``` This PR fixes the issue by forcing the problematic step in listDatabases to be executed with non-legacy mode, so that the value returned is guaranteed to be quoted. ### Why are the changes needed?
