Question

我试图远程连接到我的累计实例，我使用maven启动了一个项目并添加了所需的所有库，在此代码中，我设置了连接参数：

   public class App{


    public static void main(String [] argv){
        HashMap<String,String> parametres=new HashMap<>();
        parametres.put("accumulo.instance.id","******");
        parametres.put("accumulo.zookeepers","accumulo-do");
        parametres.put("accumulo.user","root");
        parametres.put("accumulo.password","****");
        parametres.put("accumulo.catalog","*******");

        try
        {
            DataStore dataStore= DataStoreFinder.getDataStore(parametres);
            System.out.println("Succés");
        }catch (Exception e){
            System.out.println("Exception de Accumulo");
            System.out.println(e);
        }



       }
    }

但是我试图运行它，但是出现了这个错误：

您能告诉我此错误的原因吗？我没有在Windows上使用hadoop，我的hadoop集群在linux上运行如何预防呢？

关于hadoop winutils.exe
