Exception when using scala to call java sdk，and run with Spark

Spark Connector
1

I write some very simple Scala codes followed，these codes make a Spark job，and write something into Couchbase. But when I run this job on Spark,I got an exception.I am wondeing how this happend.
Something must be pointed, if I don’t use Spark , the code can work.

CODE LIST:

import java.net.URI
import com.couchbase.client.CouchbaseClient
import scala.collection.JavaConversions._
import scala.collection.mutable.ArrayBuffer
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf

object Run {
def main(args: Array[String]){
val conf = new SparkConf(true)
val sc = new SparkContext(“local”, “test”, conf)
var nodes = ArrayBuffer(URI.create(“http://127.0.0.1:8091/pools”))
var client = new CouchbaseClient(nodes, “Result”, “”)
client.set(“hello”,“hello, world”)
var result = client.get(“hello”)
println(result)
client.shutdown()
System.exit(0)
}
}

Exception:

@sunchen hey, this topic is quite old but I wanted to point out that we now have an official spark connector! You can check it out here: http://developer.couchbase.com/documentation/server/4.0/connectors/spark-1.0/spark-intro.html
