我已经在四节点集群上安装了Hadoop。我还在每个服务器上都安装了Apache Spark。我可以在没有密码的情况下将ssh从主机发送到每个从机。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：

（我的计算机名为lebron（主计算机），kyrie，jr，doublet（工作人员））
请帮忙！！！
看起来/ opt / spark文件夹没有写日志文件的权限，请授予完全权限：-sudo chmod -R 777 / opt / spark并检查/ opt / spark文件夹user：group是否对所有机器（主机和从机都），否则运行此命令sudo chown -R userName：groupName / opt / spark
