Hyukjin Kwon 7d7c9915bb [SPARK-36788][SQL] Change log level of AQE for non-supported plans from warning to debug ### What changes were proposed in this pull request? This PR suppresses the warnings for plans where AQE is not supported. Currently we show the warnings such as: ``` org.apache.spark.sql.execution.adaptive.InsertAdaptiveSparkPlan: spark.sql.adaptive.enabled is enabled but is not supported for query: Sort [a#324881 DESC NULLS FIRST], true, 23 +- Scan ExistingRDD[a#324881] ``` for every plan that AQE is not supported. ### Why are the changes needed? It's too noisy now. Below is the example of `SortSuite` run: ``` 14:51:40.675 WARN org.apache.spark.sql.execution.adaptive.InsertAdaptiveSparkPlan: spark.sql.adaptive.enabled is enabled but is not supported for query: Sort [a#324881 DESC NULLS FIRST], true, 23 +- Scan ExistingRDD[a#324881] .

Yes, it will show less warnings to users. Note that AQE is enabled by default from Spark 3.2, see SPARK-33679 ### How was this patch tested? Manually tested via unittests. Closes #34026 from HyukjinKwon/minor-log-level.

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.
