我正在 spark 中尝试一个简单的电影推荐机器学习程序。Spark 版本：2.1.1 Java 版本：java 8 Scala 版本：Scala 代码运行器版本 2.11.7 环境：windows 7
运行这些命令来启动 master 和 worker slave
//start master
spark-class org.apache.spark.deploy.master.Master
//start worker
spark-class org.apache.spark.deploy.worker.Worker spark://valid ip:7077
我正在尝试一个非常简单的电影推荐代码：http: //blogs.quovantis.com/recommendation-engine-using-apache-spark/
我已将代码更新为：
SparkConf conf = new SparkConf().setAppName("Collaborative Filtering Example").setMaster("spark://valid ip:7077");
conf.setJars(new String[] {"C:\\Spark2.1.1\\spark-2.1.1-bin-hadoop2.7\\jars\\spark-mllib_2.11-2.1.1.jar"});
我无法通过 intelliJ 运行它运行 mvn clean install 并将 jar 复制到文件夹不起作用。我用来运行的命令：
bin\spark-submit --verbose –-jars jars\spark-mllib_2.11-2.1.1.jar –-class “com.abc.enterprise.RecommendationEngine” –-master spark://valid ip:7077 C:\Spark2.1.1\spark-2.1.1-bin-hadoop2.7\spark-mllib-example\spark-poc-1.0-SNAPSHOT.jar C:\Spark2.1.1\spark-2.1.1-bin-hadoop2.7\spark-mllib-example\ratings.csv C:\Spark2.1.1\spark-2.1.1-bin-hadoop2.7\spark-mllib-example\movies.csv 10
我看到的错误是：
C:\Spark2.1.1\spark-2.1.1-bin-hadoop2.7>bin\spark-submit --verbose --class "com.sandc.enterprise.RecommendationEngine" --master spark://10.64.98.101:7077 C:\Spark2.1.1\spark-2.1.1-

Error: Cannot load main class from JAR file:/C:/Spark2.1.1/spark-2.1.1-bin-hadoop2.7/û-class
Run with --help for usage help or --verbose for debug output
如果我给出 --jar 命令，它会给出错误：
Error: Cannot load main class from JAR file:/C:/Spark2.1.1/spark-2.1.1-bin-hadoop2.7/û-jars
有什么想法可以提交这份工作来激发火花吗？
