             Summary: Support PyArrow's feature to raise an error for unsafe 
cast
                 Key: SPARK-25811
                 URL: https://issues.apache.org/jira/browse/SPARK-25811
             Project: Spark
          Issue Type: Improvement
          Components: PySpark
    Affects Versions: 3.0.0
            Reporter: Liang-Chi Hsieh


Since 0.11.0, PyArrow supports to raise an error for unsafe cast. We should use 
it to raise a proper error for pandas udf users when such cast is detected.

We can also add a config to control such behavior.
