Hi,
Instead of use writeAsText you have a writeAsCsv
https://ci.apache.org/projects/flink/flink-docs-master/api/java/org/apache/flink/streaming/api/datastream/DataStream.html
You can use just with the string path (like you have) or you can use the
overwrite flag if it suit your needs.
Best Regards,
Fábio Dias.
