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());
}
});
