             Summary: Remove tableEnv in DataSetConversions#toTable and DataStreamConversions#toTable
                 Key: FLINK-10873
                 URL: https://issues.apache.org/jira/browse/FLINK-10873
             Project: Flink
          Issue Type: Improvement
            Reporter: Jeff Zhang


What I would like to achieve is to change the following code
{code}
    val table = data.flatMap(line=>line.split("\\s"))
      .map(w => (w, 1))
      .toTable(tEnv, 'word, 'count)
{code}

to this

{code}
    val table = data.flatMap(line=>line.split("\\s"))
      .map(w => (w, 1))
      .toTable('word, 'count)
{code}

The only change is that tableEnv is removed in method toTable.  I think the second piece of code is more readable. We can create TableEnvironment based on the ExecutionEnvironment of DataSet/DataStream rather than asking user to pass it explicitly.
