spark-submit ClassNotFound Exception with Maven

问题

I realize there are related questions with this one, but I just can't get my code to work.

I am running a Spark Streaming application in standalone mode, with the master node in my Windows host and a worker in an Ubuntu virtual machine. Here is the problem: when I run spark-submit, this is what shows up:

 >spark-submit --master spark://192.168.56.1:7077 --class spark.example.Main  C:/Users/Manuel Mourato/xxx/target/ParkMonitor-1.0-SNAPSHOT.jar
Warning: Skip remote jar C:/Users/Manuel.

    at org.apache.spark.deploy.SparkSubmit$.main(SparkSubmit.scala:121)
    at org.apache.spark.deploy.SparkSubmit.main(SparkSubmit.scala)

I created this jar file with Maven, using "package" in IntelliJ. This is how I am setting up my SparkStreaming Context:

 SparkConf sparkConfiguration= new SparkConf().setAppName("ParkingDataAnalysis").setMaster("spark://192.168.56.1:7077");
 JavaStreamingContext sparkStrContext=new JavaStreamingContext(sparkConfiguration, Durations.seconds(1));

Can anyone help me? Thank you so much.

You've got space in folder name, please add quotes (") and try again

spark-submit --master spark://192.168.56.1:7077 --class spark.example.Main "C:/Users/Manuel Mourato/xxx/target/ParkMonitor-1.0-SNAPSHOT.jar"

One more, from docs: application-jar: Path to a bundled jar including your application and all dependencies. The URL must be globally visible inside of your cluster, for instance, an hdfs:// path or a file:// path that is present on all nodes.

So please copy your file to HDFS or to the same location on all nodes. It would be difficult in combination of Linux and Windows ;) I strongly recommend setting up HDFS
