## What changes were proposed in this pull request? Create Hive Partitioned Table without specifying data type for partition column will success unexpectedly. ```HiveQL // create a hive table partition by b, but the data type of b isn't specified. CREATE TABLE tbl(a int) PARTITIONED BY (b) STORED AS parquet ``` In https://issues.apache.org/jira/browse/SPARK-26435 , PARTITIONED BY clause are extended to support Hive CTAS as following: ```ANTLR // Before (PARTITIONED BY '(' partitionColumns=colTypeList ')' // After (PARTITIONED BY '(' partitionColumns=colTypeList ')'| PARTITIONED BY partitionColumnNames=identifierList) | ``` Create Table Statement like above case will pass the syntax check, and recognized as (PARTITIONED BY partitionColumnNames=identifierList) 。 This PR will check this case in visitCreateHiveTable and throw a exception which contains explicit error message to user. ## How was this patch tested? Added tests. Closes #25390 from lidinghao/hive-ddl-fix. Authored-by: lihao <lihaowhu@gmail.com> Signed-off-by: Wenchen Fan <wenchen@databricks.com> |

Spark SQL
This module provides support for executing relational queries expressed in either SQL or the DataFrame/Dataset API.
Spark SQL is broken up into four subprojects:
- Catalyst (sql/catalyst) - An implementation-agnostic framework for manipulating trees of relational operators and expressions.
- Execution (sql/core) - A query planner / execution engine for translating Catalyst's logical query plans into Spark RDDs. This component also includes a new public interface, SQLContext, that allows users to execute SQL or LINQ statements against existing RDDs and Parquet files.
- Hive Support (sql/hive) - Includes an extension of SQLContext called HiveContext that allows users to write queries using a subset of HiveQL and access data from a Hive Metastore using Hive SerDes. There are also wrappers that allow users to run queries that include Hive UDFs, UDAFs, and UDTFs.
- HiveServer and CLI support (sql/hive-thriftserver) - Includes support for the SQL CLI (bin/spark-sql) and a HiveServer2 (for JDBC/ODBC) compatible server.
Running ./sql/create-docs.sh
generates SQL documentation for built-in functions under sql/site
