在服务器 UI 上看不到任何正在运行的应用程序答案

【问题标题】：Do not see any running application on sever UI在服务器 UI 上看不到任何正在运行的应用程序

【问题描述】：

感谢本地的 SparklyR，我正在尝试连接到我的 Spark 服务器。实际上，在我的服务器上，我打开一个 R 会话并执行

library(sparklyr)
library(dplyr)
sc <- spark_connect(master = "local")

我没有收到错误消息，但是当我在

上打开服务器 UI 时

http://my.server.local:8080/

我没有看到任何正在运行的应用程序。所以我猜有问题？

当我直接打开 SparkR 控制台时，我能够看到正在运行的应用程序。我真的很想与 SparklyR 合作，我该怎么做？

【问题讨论】：

您尝试了端口 8081、7077 还是 4040 吗？

那么 Spark UI 应该可以在 http://localhost:4040/ 获得
