Hadoop 启动apachespark集群

我已经在我的四节点集群上安装了Hadoop。我还为每一台安装了ApacheSpark。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。我也可以很好地启动主节点。但是，当我尝试使用/opt/Spark/sbin/start-all.sh运行Spark时，会出现以下错误：

请帮忙

在所有节点上配置无密码ssh

看起来/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 还要检查/opt/spark folder user:group对于所有机器（主设备和从设备）是否具有相同的值，否则请运行此命令 sudo chown-R用户名：groupName/opt/spark启动服务器：

要启动独立主服务器，请执行以下操作：

$ ./sbin/start-master.sh

要启动一个或多个辅助进程并通过以下方式将其连接到主进程：

$ ./sbin/start-slave.sh <master-spark-URL>

$。/sbin/start-slave.sh
