java.lang.IllegalArgumentException: Unable to create serializer com.esotericsoftware.kryo.serializers.FieldSerializer

Hi All,
I am trying to move away from spark-shell to spark-submit and have been making 
some code changes.  However, I am now having problem with serialization. It 
used to work fine before the code update. Not sure what I did wrong. However, 
here is the code
JaccardScore.scala
package approxstrmatch
class JaccardScore {
  val mjc = new Jaccard() with Serializable
 def main(args: Array[String]) {
  val conf = new 
SparkConf().setAppName(ApproxStrMatch).set(spark.storage.memoryFraction, 
0.0)  conf.set(spark.serializer, 
org.apache.spark.serializer.KryoSerializer)  
conf.set(spark.kryo.registrator, approxstrmatch.MyRegistrator)
   val sc = new SparkContext(conf)   // More code here…   
score.calculateSortedJaccardScore(srcFile, distFile)   sc.stop()
  }
def calculateSortedJaccardScore (sourcerdd: RDD[String], destrdd: RDD[String])  
{ // Code over here…}
