知道为什么吗？谢谢

更新

下面的命令对吗？

./spark-submit --master spark://192.168.42.80:32141 --deploy-mode cluster file:///home/me/workspace/myproj/target/scala-2.11/myproj-assembly-0.1.0.jar

更新

我想我对 spark 以及为什么我遇到这个问题和spark-submit error: ClassNotFoundException有了更多的了解。关键是这里虽然用了REST这个词，但是REST URL: spark://127.0.1.1:6066 (cluster mode)提交后应用jar并不会上传到集群，这和我的理解不一样。所以，spark集群找不到应用jar，也无法加载主类。

我将尝试找到如何设置火花集群并使用集群模式提交申请。不知道客户端模式是否会为流式作业使用更多资源。

这就是为什么您必须在主节点中找到 jar 文件或在 spark 提交之前将其放入 hdfs 的原因。

这是如何做到的： 1.）使用 ubuntu 命令将文件传输到主节点

$ scp <file> <username>@<IP address or hostname>:<Destination>

例如：

$ scp mytext.txt tom@128.140.133.124:~/

2.) 将文件传输到 HDFS：

$ hdfs dfs -put mytext.txt

希望我能帮助你。

独立模式集群想要将 jar 文件传递​​给 hdfs，因为驱动程序位于集群中的任何节点上。

hdfs dfs -put xxx.jar /user/
