@HyukjinKwon I have a problem why we change version of spark.sql.execution.pandas.udf.buffer.size to 3.0.0? Because branch-3.0 not exists this config.
Although branch-3.0 have spark.sql.pandas.udf.buffer.size. I think the since version of spark.sql.execution.pandas.udf.buffer.size is still 3.1.0. Maybe I lost something.

[HyukjinKwon]

@beliefer, thanks for pointing it out. It has to be spark.sql.execution.pandas.udf.buffer.size because it was renamed #27450 .I backported #27450 too.

Now it should be fine in branch-3.0:
