Terry Kim 809b88a162 [SPARK-36006][SQL] Migrate ALTER TABLE ... ADD/REPLACE COLUMNS commands to use UnresolvedTable to resolve the identifier ... ### What changes were proposed in this pull request? This PR proposes to migrate the following `ALTER TABLE ... ADD/REPLACE COLUMNS` commands to use `UnresolvedTable` as a `child` to resolve the table identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing). ### Why are the changes needed? This is a part of effort to make the relation lookup behavior consistent: [SPARK-29900](https://issues.apache.org/jira/browse/SPARK-29900). ### Does this PR introduce _any_ user-facing change? After this PR, the above `ALTER TABLE ... ADD/REPLACE COLUMNS` commands will have a consistent resolution behavior. ### How was this patch tested? Updated existing tests. Closes #33200 from imback82/alter_add_cols. Authored-by: Terry Kim <yuminkim@gmail.com> Signed-off-by: Wenchen Fan <wenchen@databricks.com>		2021-07-28 14:00:29 +08:00
