Hi,
please have a look at the programming guide on how to write results to an
output file:
http://ci.apache.org/projects/flink/flink-docs-master/apis/programming_guide.html#data-sinks
In your case, I would recommend:
customers.writeAsFormattedText("file:///path/to/the/result/file",
new TextFormatter<Customer3>>() {
public String format (Customer3 value) {
return value.getField(2).toString();
}
});
