             Summary: Fix applyInPandasWithStatePythonRunner to output rows that have Null as first column value
                 Key: SPARK-44464
                 URL: https://issues.apache.org/jira/browse/SPARK-44464
             Project: Spark
          Issue Type: Bug
          Components: Structured Streaming
    Affects Versions: 3.3.3
            Reporter: Siying Dong


The current implementation of {{ApplyInPandasWithStatePythonRunner}} cannot deal with outputs where the first column of the row is {{{}null{}}}, as it cannot distinguish the case where the column is null, or the field is filled as the number of data records are smaller than state records.
