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

             Summary: Allow write DataSet without path parameter
                 Key: FLINK-10218
                 URL: https://issues.apache.org/jira/browse/FLINK-10218
             Project: Flink
          Issue Type: Improvement
          Components: DataSet API
    Affects Versions: 1.6.0
            Reporter: Paul Lin


Currently, DataSet API has two overloaded write methods for using FileOutputFormat as output format, and both require a path parameter, but the output path could already be set in the FileOutputFormat object. What's more, the subclasses of FileOutputFormat mostly don't have default constructors and required a path parameter too, so users have to set output path twice in the code, like:
{code:java}
  String output = "hdfs:///tmp/";
  dataset.write(new TextOutputFormat<>(new Path(output)), output);
{code}
So I propose to add another write method that requires no path parameter. May someone assign this issue to me?
