我在我的四节点集群上安装了Hadoop。我还在每个上安装了Apache Spark。我可以在没有密码的情况下从主服务器ssh到每个从服务器。我也可以启动我的主节点。但是，当我尝试使用/opt/spark/sbin/start-all.sh运行Spark时，出现以下错误：

启动服务器：
要启动独立主服务器，请执行：
$ ./sbin/start-master.sh
启动一个或多个工人并通过以下方式将他们连接到主人：
$ ./sbin/start-slave.sh <master-spark-URL>

看起来像/ opt / spark文件夹没有写入日志文件的权限 给予完全许可： - sudo chmod -R 777 / opt / spark 并检查/ opt / spark文件夹user：group是否为所有机器（主机和从机都有）具有相同的值，否则运行此命令 sudo chown -R userName：groupName / opt / spark

在所有节点上配置密码少ssh。
