Hi Marco,
Here is what my code looks like
Config config = new Config("hello");
SparkConf sparkConf = config.buildSparkConfig();
sparkConf.setJars(JavaSparkContext.jarOfClass(Driver.class));
JavaStreamingContext ssc = new JavaStreamingContext(sparkConf, new
Duration(config.getSparkStremingBatchInterval()));
ssc.sparkContext().setLogLevel("ERROR");
NSQReceiver sparkStreamingReceiver = new NSQReceiver(config, "input_test");
JavaReceiverInputDStream<String> jsonMessagesDStream =
ssc.receiverStream(sparkStreamingReceiver);
NSQProducer producer = new NSQProducer()
.addAddress(config.getServerConfig().getProperty("NSQD_IP"),
Integer.parseInt(config.getServerConfig().getProperty("NSQD_PORT")))
.start();
jsonMessagesDStream
.mapToPair(new PairFunction<String, String, Integer>() {
@Override
public Tuple2<String, Integer> call(String s) throws Exception {
JsonParser parser = new JsonParser();
JsonObject jsonObj = parser.parse(s).getAsJsonObject();
if (jsonObj != null && jsonObj.has("var1") ) {
JsonObject transactionObject =
jsonObj.get("var1").getAsJsonObject();
if(transactionObject != null &&
transactionObject.has("var2")) {
String key =
transactionObject.get("var2").getAsString();
return new Tuple2<>(key, 1);
}
}
return new Tuple2<>("", 0);
}
}).reduceByKey(new Function2<Integer, Integer, Integer>() {
@Override
public Integer call(Integer v1, Integer v2) throws Exception {
return v1+v2;
}
}).foreachRDD(new VoidFunction<JavaPairRDD<String, Integer>>() {
@Override
public void call(JavaPairRDD<String, Integer>
stringIntegerJavaPairRDD) throws Exception {
Map<String, Integer> map = new HashMap<>();
Gson gson = new Gson();
stringIntegerJavaPairRDD
.collect()
.forEach((Tuple2<String, Integer> KV) -> {
String status = KV._1();
Integer count = KV._2();
map.put(status, count);
}
);
NSQReceiver.send(producer, "output_777",
gson.toJson(map).getBytes());
}
});
Thanks,
kant
