Here is another transformation that might cause the error but it has to be one of these two since I only have two transformations
jsonMessagesDStream .window(new Duration(60000), new Duration(1000)) .mapToPair(new PairFunction<String, String, Long>() { @Override public Tuple2<String, Long> call(String s) throws Exception { //System.out.println(s + " *****************************"); JsonParser parser = new JsonParser(); JsonObject jsonObj = parser.parse(s).getAsJsonObject(); if (jsonObj != null && jsonObj.has("var1")) { JsonObject jsonObject = jsonObj.get("var1").getAsJsonObject(); if (jsonObject != null && jsonObject.has("var2") && jsonObject.get("var2").getAsBoolean() && jsonObject.has("var3") ) { long num = jsonObject.get("var3").getAsLong(); return new Tuple2<String, Long>("var3", num); } } return new Tuple2<String, Long>("var3", 0L); } }).reduceByKey(new Function2<Long, Long, Long>() { @Override public Long call(Long v1, Long v2) throws Exception { return v1+v2; } }).foreachRDD(new VoidFunction<JavaPairRDD<String, Long>>() { @Override public void call(JavaPairRDD<String, Long> stringIntegerJavaPairRDD) throws Exception { Map<String, Long> map = new HashMap<>(); Gson gson = new Gson(); stringIntegerJavaPairRDD .collect() .forEach((Tuple2<String, Long> KV) -> { String status = KV._1(); Long count = KV._2(); map.put(status, count); } ); NSQReceiver.send(producer, "dashboard", gson.toJson(map).getBytes()); } }); On Wed, Nov 30, 2016 at 10:40 PM, kant kodali <kanth...@gmail.com> wrote: > 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 > > > On Wed, Nov 30, 2016 at 2:11 PM, Marco Mistroni <mmistr...@gmail.com> > wrote: > >> Could you paste reproducible snippet code? >> Kr >> >> On 30 Nov 2016 9:08 pm, "kant kodali" <kanth...@gmail.com> wrote: >> >>> I have lot of these exceptions happening >>> >>> java.lang.Exception: Could not compute split, block >>> input-0-1480539568000 not found >>> >>> >>> Any ideas what this could be? >>> >> >
