Hello all, I am getting the below error on execute of StreamExecutionEnvironment.
*Caused by: java.lang.IllegalStateException: Iteration FeedbackTransformation{id=15, name='Feedback', outputType=PojoType<wikiedits.StockAnalysis$Centroid, fields = [id: String, pt: BasicArrayTypeInfo<Double>]>, parallelism=4} does not have any feedback edges.* The run method inside the thread class of DataStreamUtils handles this exception: @Override public void run(){ try { stream.getExecutionEnvironment().execute(); } catch (Exception e) { throw new RuntimeException("Exception in execute()", e); } } I am not able to understand what to infer from this error message so that I could solve it. Best Regards, Subash Basnet
