----------------------------------

             Summary: Should throws some useful messages when statefulParDo use 
non-KV input
                 Key: BEAM-2486
                 URL: https://issues.apache.org/jira/browse/BEAM-2486
             Project: Beam
          Issue Type: Improvement
          Components: runner-core, runner-flink
            Reporter: Jingsong Lee


Now Flink runner will throws a ClassCastException without detail messages when 
a statefulParDo use non-KV input. It is not easy for users to find errors and 
causes.
