Scala/Spark:原因: java.lang.ClassNotFoundException: org.apache.spark.Logging

Question

我是scala和spark的新手。尝试修复我的spark/scala开发设置。我被版本和缺少的jars搞糊涂了。我在stackoverflow上搜索了一下，但仍然停留在这个问题上。可能是某些东西丢失或配置错误。

运行命令：

me@Mycomputer:~/spark-2.1.0$ bin/spark-submit --class ETLApp /home/me/src/etl/target/scala-2.10/etl-assembly-0.1.0.jar

输出：

...
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/spark/Logging
...
Caused by: java.lang.ClassNotFoundException: org.apache.spark.Logging

build.sbt：

name := "etl"

version := "0.1.0"
scalaVersion := "2.10.5"
javacOptions ++= Seq("-source", "1.8", "-target", "1.8")
mainClass := Some("ETLApp")

libraryDependencies += "org.apache.spark" %% "spark-core" % "1.5.2" % "provided";
libraryDependencies += "org.apache.spark" %% "spark-sql" % "1.5.2" % "provided";
libraryDependencies += "org.apache.spark" %% "spark-streaming" % "1.5.2" % "provided";
libraryDependencies += "org.apache.spark" %% "spark-streaming-kafka" % "1.5.2";
libraryDependencies += "com.datastax.spark"  %% "spark-cassandra-connector" % "1.5.0-M2";
libraryDependencies += "org.apache.curator" % "curator-recipes" % "2.6.0"
libraryDependencies += "org.apache.curator" % "curator-test" % "2.6.0"
libraryDependencies += "args4j" % "args4j" % "2.32"

java -version java版本"1.8.0_101“

scala -version 2.10.5

spark版本2.1.0

欢迎任何提示。谢谢
