我正在尝试使用spark-submit运行本地jar文件，效果很好。这是命令-

spark-submit --class "SimpleApp" --master local myProject/target/scala-2.11/simple-project_2.11-1.0.jar

但是当我尝试卷曲时

curl -X POST --data '{
 "file": "file:///home/user/myProject/target/scala-2.11/simple-project_2.11-1.0.jar",
 "className": "SimpleApp",
}'  
-H 
"Content-Type: application/json" 
http://server:8998/batches

它抛出错误

"requirement failed: Local path /home/user/myProject/target/scala-2.11/simple-project_2.11-1.0.jar cannot be added to user sessions."

这是我的livy.conf文件，因为有些文章建议更改一些内容。

# What host address to start the server on. By default, Livy will bind to all network interfaces.
livy.server.host = 0.0.0.0

# What port to start the server on.
livy.server.port = 8998

# What spark master Livy sessions should use.
livy.spark.master = local

如何在 Windows 窗体应用程序中从 JAVASCRIPT 调用 C# 函数（在 HTML 代码中，我通过 CefSharp 调用）

CefSharp 组件

public partial class Form1 : Form
{
    public ChromiumWebBrowser chromeBrowser;

    public Form1()
    {
        InitializeComponent();

        // Start the browser after initialize global component
        InitializeChromium();
    }

    public void InitializeChromium()
    {

        CefSettings settings = new CefSettings();

        settings.CefCommandLineArgs.Add("enable-media-stream", "1");

        Cef.Initialize(settings);

        chromeBrowser = new ChromiumWebBrowser("localhost/myproject/index.html");

        this.Controls.Add(chromeBrowser);

        chromeBrowser.Dock = DockStyle.Fill;
    }
}

JS调用的函数

public void Test(String message)
{
    MessageBox.Show(message, "Test");
}

HTML 代码 我需要在 onclick 事件中调用 Test()

<span class="mySpan" onclick="<Some>.Test('It is working');"></span>

我尝试过的代码， …
