Takeshi Yamamuro 2a4dd6f06c [SPARK-24681][SQL] Verify nested column names in Hive metastore 
## What changes were proposed in this pull request?
This pr added code to check if nested column names do not include ',', ':', and ';' because Hive metastore can't handle these characters in nested column names;
ref: https://github.com/apache/hive/blob/release-1.2.1/serde/src/java/org/apache/hadoop/hive/serde2/typeinfo/TypeInfoUtils.java#L239

## How was this patch tested?
Added tests in `HiveDDLSuite`.

Author: Takeshi Yamamuro <yamamuro@apache.org>

Closes #21711 from maropu/SPARK-24681.

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.
