Hadoop启动DataNode的过程涉及多个步骤，确保集群的正常运行至关重要。首先，你需要进入Hadoop的bin目录，通常通过执行cd命令实现。进入该目录后，进行NameNode的格式化操作，这是启动DataNode前的必要步骤，通过执行hadoop namenode -format命令来完成。完成上述步骤后，接下来启动Hadoop的所有进程。这里推荐使用st...

原因: hadoop3.0以后slaves更名为workers。。。,直接在master节点的hadoop下配置文件workers填写子节点的主机名或ip地址即可 请修改完master节点后,同步修改到所有slave节点的worker文件 然后重新启动hdf与yarn,数据节点进程正常启动了:
