------------------------------------
Summary: Add warning when pandas >= 3.0.0 is used with PySpark
Key: SPARK-55965
URL: https://issues.apache.org/jira/browse/SPARK-55965
Project: Spark
Issue Type: Improvement
Components: PySpark
Affects Versions: 4.0.0
Reporter: Yicong Huang
PySpark does not yet fully support pandas >= 3.0.0. In particular, pandas 3.0
defaults future.infer_string to True, which causes string columns to use
pa.large_string() internally. This can lead to Arrow type mismatches during
createDataFrame/toPandas round-trips.
This PR adds a FutureWarning in require_minimum_pandas_version() to notify
users that pandas >= 3.0.0 is not yet fully supported.
