New line lost in streaming output file

[Ashutosh Kumar]

I am getting multiple empty files for streaming output for each interval.
To Avoid this I tried

     kStream.foreachRDD(new VoidFunction2<JavaRDD<String>,Time>(){





*public void call(JavaRDD<String> rdd,Time time) throws Exception {
            if(!rdd.isEmpty()){
rdd.saveAsTextFile("filename_"+time.milliseconds()+".csv");
    }                }*
This prevents writing of empty files. However this appends line after one
another by removing new lines. All lines are merged.
How do I retain my new line?

Thanks
