jzhuge commented on a change in pull request #25330: [SPARK-28565][SQL] DataFrameWriter saveAsTable support for V2 catalogs URL: https://github.com/apache/spark/pull/25330#discussion_r311324593
########## File path: sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala ########## @@ -648,8 +648,11 @@ class Analyzer( if catalog.isTemporaryTable(ident) => u // temporary views take precedence over catalog table names - case u @ UnresolvedRelation(CatalogObjectIdentifier(Some(catalogPlugin), ident)) => - loadTable(catalogPlugin, ident).map(DataSourceV2Relation.create).getOrElse(u) + case u @ UnresolvedRelation(CatalogObjectIdentifier(maybeCatalog, ident)) => + maybeCatalog.orElse(sessionCatalog) Review comment: This changes the SELECT path, so more unit tests for table relation are needed, e.g.: ``` test("Relation: basic") { val t1 = "tbl" withTable(t1) { sql(s"CREATE TABLE $t1 USING $v2Format AS SELECT id, data FROM source") checkAnswer(spark.table(t1), spark.table("source")) checkAnswer(sql(s"TABLE $t1"), spark.table("source")) checkAnswer(sql(s"SELECT * FROM $t1"), spark.table("source")) } } ``` IMHO this change v2 session catalog and related tests in `DataSourceV2SessionDataFrameSuite` can be split to a separate PR with additional unit tests for SQL SELECT and spark.table(). Another PR to update `ResolveInsertInto` to support v2 session catalog in SQL INSERT INTO and DFW.insertInto. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
