I have this error when I try to connect to cassandra with spark-cassandra-connector:
Exception in thread "main" java.lang.NoClassDefFoundError: com/datastax/driver/core/ProtocolOptions$Compression at com.datastax.spark.connector.cql.CassandraConnectorConf$.(CassandraConnectorConf.scala:112) at com.datastax.spark.connector.cql.CassandraConnectorConf$.(CassandraConnectorConf.scala) at com.datastax.spark.connector.cql.CassandraConnector$.apply(CassandraConnector.scala:192) at com.datastax.spark.connector.SparkContextFunctions.cassandraTable$default$3(SparkContextFunctions.scala:48) at main.scala.TestSpark$.main(TestSpark.scala:19) at main.scala.TestSpark.main(TestSpark.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.spark.deploy.SparkSubmit$.org$apache$spark$deploy$SparkSubmit$$runMain(SparkSubmit.scala:672) at org.apache.spark.deploy.SparkSubmit$.doRunMain$1(SparkSubmit.scala:180) at org.apache.spark.deploy.SparkSubmit$.submit(SparkSubmit.scala:205) at org.apache.spark.deploy.SparkSubmit$.main(SparkSubmit.scala:120) at org.apache.spark.deploy.SparkSubmit.main(SparkSubmit.scala) Caused by: java.lang.ClassNotFoundException: com.datastax.driver.core.ProtocolOptions$Compression at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) ... 15 more I have added the jar in the spark class path spark-cassandra-connector_2.11-1.5.0-M2.jar
I have added the dependencies in the sbt file:
name := "Simple Project"
version := "1.0"
scalaVersion := "2.11.7"
libraryDependencies += "org.apache.spark" %% "spark-core" % "1.5.1"
libraryDependencies += "org.apache.spark" %% "spark-sql" % "1.5.1"
libraryDependencies += "com.datastax.spark" %% "spark-cassandra-connector" % "1.5.0-M2"
libraryDependencies += "com.datastax.spark" %% "spark-cassandra-connector-java" % "1.5.0-M2"
This is the scala program I try to execute:
package main.scala
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf
import com.datastax.spark.connector._
/**
* Created by Simo on 01.12.15.
*/
object TestSpark {
def main(args: Array[String]) {
val conf = new SparkConf(true)
.set("spark.cassandra.connection.host", "54.229.218.236")
.setAppName("Simple Application")
val sc= new SparkContext("local", "test", conf)
val rdd = sc.cassandraTable("test", "kv")
println(rdd.count)
println(rdd.first)
println(rdd.map(_.getInt("value")).sum)
}
}
And this is how i run it:
$ sbt package
$ $SPARK_HOME/bin/spark-submit --class "main.scala.TestSpark" target/scala-2.11/simple-project_2.11-1.0.jar
Can you help me to understand what I'm doing wrong?
Thanks!
Edit:
I have tried to add the Datastax driver in the dependencies list and in the spark classpath:
libraryDependencies += "com.datastax.cassandra" % "cassandra-driver-core" % "2.1.9"
libraryDependencies += "com.datastax.cassandra" % "cassandra-driver-mapping" % "2.1.9"
The last error no longer appear but now I have another error:

Edit 2: Make scala 2.10.6 at compile time (same as the scala version of spark) The previous error no longer appear but i have this new error:

最终使用@Odomontois建议的sbt-assembly解决
这是最终版本。sbt:

您还需要从以下位置添加Datastax Cassandra驱动程序的依赖项(根据Spark-cassandra连接器的版本):- https://repo1.maven.org/maven2/com/datastax/cassandra/cassandra-driver-core/
