我创建了一个hadoop集群，其中有1个主节点和2个从节点。所有服务都在节点中运行。datanode和nodemanager在slave1和slave2上处于活动状态。namenode、datanode、nodemanager、resourcemanager和secondarynamenode在主节点上处于活动状态。但是namenode的web用户界面( localhost:50070 )部分活动节点显示1个节点（主节点），而yarn的web ui显示1个活动节点。
完成以下工作：
禁用防火墙。
所有节点之间的无密码ssh连接。
主机名配置。
将hadoop配置文件从主设备传输到从设备。
如何解决这个问题？
