Hi, This is the streaming program I have for trade prices following the doc for result set for tables
https://flink.apache.org/news/2017/03/29/table-sql-api-update.html val streamExecEnv = StreamExecutionEnvironment.getExecutionEnvironment val ds = streamExecEnv .addSource(new FlinkKafkaConsumer011[String](topicsValue, new SimpleStringSchema(), properties)) val splitStream = ds.map(new MapFunction[String, Tuple4[String, String, String, Float]] { override def map(value: String): Tuple4[String, String, String, Float] = { var cols = value.split(',') return (cols(0).toString, cols(1).toString, cols(2).toString, cols(3).toFloat) } }) val tableEnv = TableEnvironment.getTableEnvironment(streamExecEnv) tableEnv.registerDataStream("priceTable", splitStream, 'key, 'ticker, 'timeissued, 'price) val result = tableEnv.scan("priceTable").filter('ticker.isNotNull).select('key, 'ticker, 'timeissued, 'price) val r = result.toDataStream[Row] r.print() This compiles and runs but I do not see any ouput to screen. This is the output from Flink GUI [image: image.png] I can verify that data being streamed in so there is no issue there. However, I don't see any output and Flink GUI does not look healthy (circles). Appreciate any input.
