### What changes were proposed in this pull request? The test added by #31797 has the [failure](https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/137741/testReport/org.apache.spark.sql.catalyst.optimizer/ReplaceNullWithFalseInPredicateSuite/SPARK_34692__Support_Not_Int__and_Not_InSet__propagate_null/). This is a followup to fix it. ### Why are the changes needed? Due to #32157, the rule `ReplaceNullWithFalseInPredicate` will check tree pattern before actually doing transformation. As `null` in `INSET` is not `NULL_LITERAL` pattern, we miss it and fail the newly added `not inset ...` check in `replaceNullWithFalse`. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Existing unit tests. Closes #32278 from viirya/SPARK-34692-followup. Authored-by: Liang-Chi Hsieh <viirya@gmail.com> Signed-off-by: Dongjoon Hyun <dhyun@apple.com> |

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.
