我正在尝试通过 windows 上的 spark 提交我的 spark-mongo 代码 jar。我在独立模式下使用 spark。我在同一台机器上配置了 spark master 和两个 worker。我想用一个主人和两个工人来执行我的 jar。我正在尝试执行以下命令:spark-submit --master spark://localhost:7077 --deploy-mode cluster --executor-memory 5G --class spark.mongohadoop.testing3 G:\sparkmon1.jar
我面临以下错误:

我已经在 env 中设置了 winutil 路径。为什么我收到此错误,解决方案是什么?
