Here you go:
JavaDStream<String> textStream =
ssc.textFileStream("/home/akhld/sigmoid/");
textStream.foreachRDD(new Function<JavaRDD<String>,Void>() {
@Override
public Void call(JavaRDD<String> rdd) throws Exception {
// TODO Auto-generated method stub
rdd.foreach(new VoidFunction<String>(){
@Override
public void call(String stringData) throws Exception {
// Use this data!
System.out.println("W00t!! Data :" + stringData);
}
});
return null;
}
});
Thanks
Best Regards
