Issue in Kafka to Spark Streaming Data pipeline with python pyspark

I am using below program and runnign this in Anaconda(Spyder) for creating data pipeline from Kafka to Spark streaming & in python

import sys
from pyspark import SparkContext, SparkConf
from pyspark.streaming import StreamingContext
from pyspark.streaming.kafka import KafkaUtils
from uuid import uuid1
import os


##Step 1: Initialize sparkcontext
spark_context = SparkContext(appName="Transformation Application")

###Step 2: Initialize streaming context
ssc = StreamingContext(spark_context, 5)

def utf8_decoder(s):
    """ Decode the unicode as UTF-8 """
    if s is None:
        return None
    return s.decode('utf-8')

message = KafkaUtils.createDirectStream(ssc,topics=['testtopic'],kafkaParams={"metadata.broker.list":"localhost:9092","key.deserializer": "org.springframework.kafka.support.serializer.JsonDeserializer","value.deserializer": "org.springframework.kafka.support.serializer.JsonDeserializer"},fromOffsets=None,messageHandler=None,keyDecoder=utf8_decoder,valueDecoder=utf8_decoder)
message
words = message.map(lambda x: x[1]).flatMap(lambda x: x.split(" "))
wordcount=words.map(lambda x: (x,1)).reduceByKey(lambda a,b:a+b)
wordcount.pprint()

When I am printing message, words,wordscount i am getting no proper results,I am getting hexadecimal values .

message
Out[16]: <pyspark.streaming.kafka.KafkaDStream at 0x23f8b1f8248>

wordcount
Out[18]: <pyspark.streaming.dstream.TransformedDStream at 0x23f8b2324c8>

in my topic(testtopic) I am produced string - " Hi Hi Hi how are you doing" then wordcount should give count for each word but it is giving some encoded hexadecimal values
