Error while calling udf Spark submit

[Divya Gehlot]

Hi,
I am on Spark 1.6.1
I am getting below error when I am trying to call UDF in my spark Dataframe
column
UDF
/* get the train line */
val deriveLineFunc :(String => String) = (str:String) => {
val build_key = str.split(",").toList
val getValue  = if(build_key.length > 1)
MapBrdcst.value.getOrElse((build_key(0),build_key(1)),("no","no")) else
("no","no")
val (value:String,_) = getValue
value
}

Exception in thread "main" org.apache.spark.SparkException: Job aborted due
to stage failure: Task 0 in stage 12.0 failed 4 times, most recent failure:
Lost task 0.3 in stage 12.0 (TID 621,
ip-xxx-xx-xx-xx.ap-southeast-1.compute.internal):
java.lang.ExceptionInInitializerError



Any clue ,what went wrong


Thanks,

Divya
