> {code}
> 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()
> {code}
> 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.
