spark-cassandra连接器的Spark cassandra集成错误

Question

  bin/spark-submit --packages datastax:spark-cassandra-connector:1.6.0-s_2.10
     --class "pl.japila.spark.SparkMeApp" --master local  /home/hduser2/code14/target/scala-2.10/simple-project_2.10-1.0.jar

**name := "Simple Project"    
version := "1.0"     
scalaVersion := "2.10.4"      
libraryDependencies += "org.apache.spark" %% "spark-core" % "1.6.0"     
libraryDependencies += "org.apache.spark" %% "spark-sql" % "1.6.0"

  "org.apache.cassandra" % "cassandra-clientutil" % "3.5",      
  "com.datastax.cassandra" % "cassandra-driver-core" % "3.0.0"    
)**

package pl.japila.spark     
import org.apache.spark.sql._    
import com.datastax.spark.connector._    
import com.datastax.driver.core._

import org.apache.spark.SparkConf    
import com.datastax.driver.core._   
import com.datastax.spark.connector.rdd._   

object SparkMeApp {
  def main(args: Array[String]) {

 val conf = new SparkConf(true).set("spark.cassandra.connection.host", "127.0.0.1")

  val sc = new SparkContext("local", "test", conf)    
  val sqlContext = new org.apache.spark.sql.SQLContext(sc)    
  val rdd = sc.cassandraTable("test", "kv")    
  val collection = sc.parallelize(Seq(("cat", 30), ("fox", 40)))

collection.saveToCassandra("test", "kv", SomeColumns("key", "value"))
  }
}

我得到了一个错误：-

线程“main”java.lang.nosuchmethoderror：com.datastax.driver.core.queryoptions.setrefreshnodeintervalmillis（I）lcom/datastax/driver/core/queryoptions；**在com.datastax.spark.connector.cql.defaultConnectionFactory$.ClusterBuilder(cassandraconnectionFactory：49）在com.datastax.spark.connector.cql.在com.datastax.spark.connector.cql.cassandraconnector$$anonfun$3处应用(Cassandraconnector.scala:148)在com.datastax.spark.connector.cql.cassandraconnector$$anonfun$3处应用(Cassandraconnector.scala:148)在com.datastax.spark.connector.cql.cassandraconnector.scala:148)在在com.datastax.spark.connector.cql.Cassandraconnector.opensess获取（refcountedcache.scala:56)ion(cassandraconnector.scala:81)在com.datastax.spark.connector.cql.cassandraconnector.withsessiondo(cassandraconnector.scala:109)

使用的版本有:-
Spark-1.6.0
Scala-2.10.4
cassandra-driver-core JAR-3.0.0
cassandra version 2.2.7
spark-cassandra Connector-1.6.0-S2.10

来人帮帮我！！

Answer 1

我会从移除

libraryDependencies ++= Seq(        
  "org.apache.cassandra" % "cassandra-thrift" % "3.5" ,      
  "org.apache.cassandra" % "cassandra-clientutil" % "3.5",      
  "com.datastax.cassandra" % "cassandra-driver-core" % "3.0.0"    
)

因为作为连接器依赖项的库将自动包含在包依赖项中。

然后，我将通过启动spark-shell来测试包的分辨率

./bin/spark-shell --packages datastax:spark-cassandra-connector:1.6.0-s_2.10
