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

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.

Thanks,

Dr Mich Talebzadeh
