I have wrote 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 wondering how this happend.
Something must be pointed, if I don't use Spark , the code can work.
Some other tips:
1.the class :org.apache.http.protocol.RequestUserAgent is in package
httpcore-4.3,this package is an dependency of couchbase sdk,and this class
has the constructor function with a String param.
2.two dependicies
"com.couchbase.client" % "couchbase-client" % "1.4.4",
"org.apache.spark" %% "spark-core" % "1.0.1" % "provided"
3.I am using sbt assembly
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)
}
}
