Also it seems [SPARK-33901](https://issues.apache.org/jira/browse/SPARK-33901) (#30918) doesn't work for nested type. For instance, this test: ```scala test("SPARK-XXXXX: create table like should should not change table's schema (nested type)") { withTable( "tt") { sql(s"CREATE TABLE tt(s1 struct<i: CHAR(5), j: int>, s2 struct<c: VARCHAR(4), d: int>) " + s"USING $format") withView("t") { sql("CREATE VIEW t AS SELECT s1.i, s2.c FROM tt") checkTableSchemaTypeStr(Seq(Row("char(5)"), Row("varchar(4)"))) } } } ``` doesn't work even with this fix. It seems this is related to how the metadata is handled: in nested schema the metadata is associated with the top-level field (e.g., `s1`, `s2`) instead of leaf nodes (e.g., `i`, `c`). cc @yaooqinn @cloud-fan -- This is an automated message from the Apache Git Service.
