Hi,
What is the proper Json parsing library to use in Spark Streaming? Currently
I am trying to use Gson library in a Java class and calling the Java method
from a Scala class as shown below: What are the advantages of using Json4S
as against using Gson library in a Java class and calling it from Scala?
val lines = KafkaUtils.createStream(ssc, zkQuorum, group, topicMap).
map{case (x, y) => ((x.toString,
Utils.toJsonObject(y.toString).get("request").getAsJsonObject().get("queryString").toString))}
Thanks,
Swetha
