### What changes were proposed in this pull request? This patch fixes `Invoke` expression when the target object has more than one method with the given method name. ### Why are the changes needed? `Invoke` will find out the method on the target object with given method name. If there are more than one method with the name, currently it is undeterministic which method will be used. We should add the condition of parameter number when finding the method. ### Does this PR introduce _any_ user-facing change? Yes, fixed a bug when using `Invoke` on a object where more than one method with the given method name. ### How was this patch tested? Unit test. Closes #32404 from viirya/verify-invoke-param-len.

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.
