----------------------------------

             Summary: Unable to execute partial DAG
                 Key: FLINK-11049
                 URL: https://issues.apache.org/jira/browse/FLINK-11049
             Project: Flink
          Issue Type: Bug
          Components: Job-Submission
    Affects Versions: 1.7.0
            Reporter: Jeff Zhang


{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 the 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.
