## What changes were proposed in this pull request? This PR moves `udf_radians` from `HiveCompatibilitySuite` to `HiveQuerySuite` to make it easy to test with JDK 11 because it returns different value from JDK 9: ```java public class TestRadians { public static void main(String[] args) { System.out.println(java.lang.Math.toRadians(57.2958)); } } ``` ```sh [rootspark-3267648 ~]# javac TestRadians.java [rootspark-3267648 ~]# /usr/lib/jdk-9.0.4+11/bin/java TestRadians 1.0000003575641672 [rootspark-3267648 ~]# /usr/lib/jdk-11.0.3/bin/java TestRadians 1.0000003575641672 [rootspark-3267648 ~]# /usr/lib/jdk8u222-b10/bin/java TestRadians 1.000000357564167 ``` ## How was this patch tested? manual tests Closes #25417 from wangyum/SPARK-28686.

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
