Chaoqin Li created SPARK-49536:
----------------------------------

             Summary: Add error handling for python streaming data source record prefetching
                 Key: SPARK-49536
                 URL: https://issues.apache.org/jira/browse/SPARK-49536
             Project: Spark
          Issue Type: Task
          Components: PySpark, SS
    Affects Versions: 4.0.0
            Reporter: Chaoqin Li


Currently there is an assert that return status code from the python worker is 

SpecialLengths.START_ARROW_STREAM when python source runner is prefetching records. To improve debugability, check the status code and rethrow an runtime error with detailed error message.
