### What changes were proposed in this pull request? The newly added test fails Jenkins maven jobs, see https://github.com/apache/spark/pull/29303#discussion_r464729021 We move the test from `ThriftServerWithSparkContextSuite` to `SparkMetadataOperationSuite`, the former uses an embedded thrift server where the server and the client are in the same JVM process and the latter forks a new process to start the server where the server and client are isolated. The sbt runner seems to be fine with the test in the `ThriftServerWithSparkContextSuite`, but the maven runner with `scalates`t plugin will face the classloader issue as we will switch classloader to the one in the `sharedState` which is not the one that hive uses to load some classes. This is more like an issue that belongs to the maven runner or the `scalatest`. So in this PR, we simply move it to bypass the issue. BTW, we should test against the way of using embedded thrift server to verify whether it is just a maven issue or not, there could be some use cases with this API. ### Why are the changes needed? Jenkins recovery ### Does this PR introduce _any_ user-facing change? no ### How was this patch tested? modified uts Closes #29347 from yaooqinn/SPARK-32492-F.

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 extensions that allow 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
, and SQL configuration documentation that gets included as part of configuration.md
in the main docs
directory.
