----------------------------------
Resolution: Not A Problem
> "show create table" doesn't work for v2 table
> ---------------------------------------------
>
> Key: SPARK-34034
> URL: https://issues.apache.org/jira/browse/SPARK-34034
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Shixiong Zhu
> Priority: Blocker
> Labels: regression
>
> I was QAing Spark 3.1.0 RC1 and found one regression: "show create table"
> doesn't work for v2 table.
> But when using Spark 3.0.1, "show create table" works for v2 table.
> Steps to test:
> {code:java}
> /bin/spark-shell --packages io.delta:delta-core_2.12:0.7.0 --conf
> "spark.sql.extensions=io.delta.sql.DeltaSparkSessionExtension" --conf
> "spark.sql.catalog.spark_catalog=org.apache.spark.sql.delta.catalog.DeltaCatalog"
> scala> spark.sql("create table foo(i INT) using delta")
> res0: org.apache.spark.sql.DataFrame = []
> scala> spark.sql("show create table foo").show(false)
> +-----------------------------------------------+
> |createtab_stmt |
> +-----------------------------------------------+
> |CREATE TABLE `default`.`foo` (
> )
> USING delta
> |
> +-----------------------------------------------+
> {code}
> Looks like it's caused by [https://github.com/apache/spark/pull/30321]
> which blocks "show create table" for v2.
