用Spark和maven运行项目[复制]

Question

我正在尝试运行我的java类来读取GML文件，我使用Tinkerpop和GMLReader来实现这一点，问题是当我尝试使用spark运行它时，它会给我一个异常
我编写了一个简单的测试代码：

 public static void main(String[] args) throws IOException {
    TinkerGraph graphs = new TinkerGraph();
    String in = "/home/salma/Desktop/celegansneural.gml";
    GMLReader.inputGraph(graphs, in);
    System.out.println(graphs);
 }

我用来运行类的命令：

root@salma-SATELLITE-C855-1EQ:/usr/local/spark# ./bin/spark-submit --class graph_example.WordCount --master local[2] ~/workspace/graph_example/target/graph_example-0.0.1-SNAPSHOT.jar

错误：

Answer 1

必须提供包含TinkerGraph实现的依赖项。如果我没弄错的话，你需要提供这个罐子

然后像往常一样运行spark submit，但要使用--jars/some/location/blueprints-core-2.6.0。jar

官方文件对此进行了解释：

使用spark submit时，应用程序jar以及--jars选项中包含的任何jar将自动传输到集群。
