Aljoscha Krettek commented on FLINK-2069:
-----------------------------------------

Could you maybe share your code? I now have this example code and it still 
produces output:

{code}
DataStream<String> text = env.socketTextStream("localhost", 9999);

IterativeDataStream<Tuple2<String, Integer>> iterate = text.flatMap(new 
WordCount.Tokenizer()).iterate();

SplitDataStream<Tuple2<String, Integer>> iterEnd = iterate.map(new 
MapFunction<Tuple2<String, Integer>, Tuple2<String, Integer>>() {
    private static final long serialVersionUID = 1L;

    @Override
    public Tuple2<String, Integer> map(Tuple2<String, Integer> value) throws 
Exception {
        return new Tuple2<String, Integer>(value.f0, value.f1 + 1);
    }
}).split(new OutputSelector<Tuple2<String, Integer>>() {
    private static final long serialVersionUID = 1L;

    @Override
    public Iterable<String> select(Tuple2<String, Integer> value) {
        if (value.f1 < 10) {
            return Lists.newArrayList("iter");
        } else {
            return Lists.newArrayList("end");
        }
    }
});

iterate.closeWith(iterEnd.select("iter"));

iterEnd.select("end").writeAsCsv("/Users/aljoscha/Downloads/wc-csv-out", 
FileSystem.WriteMode.OVERWRITE).setParallelism(1);
{code}

Are you using a timeout in your {{iterate()}} call?
