Description

val benv = ExecutionEnvironment.getExecutionEnvironment
val btEnv = TableEnvironment.getTableEnvironment(benv)
val data = benv.fromElements("hello world", "hello flink", "hello hadoop")
data.writeAsText("/Users/jzhang/a.txt", FileSystem.WriteMode.OVERWRITE);
val table = data.flatMap(line=>line.split("\\s")).
  map(w => (w, 1)).
  toTable(btEnv, 'word, 'number)
btEnv.registerTable("wc", table)
btEnv.sqlQuery("select word, count(1) from wc group by word").
  toDataSet[Row].print()

In the above example, the last statement will trigger 2 job execution (writeAsText and print), but what user expect is the print job. The root cause is that currently, flink unable to submit partial dag.
