问题

could only be written to 0 of the 1 minReplication nodes. There are 0 datanode(s) running and 0 node(s) are excluded in this operation.
造成这个问题的原因可能是使用hadoop namenode -format格式化时格式化了多次造成那么spaceID不一致

解决方案

停止集群（切换到安装目录下）
sbin/stop-all.sh

删除以下目录，再重新初始化
rm -rf /opt/module/hadoop-3.1.3/data
rm -rf /opt/module/hadoop-3.1.3/logs

在这里插入图片描述
初始化详见
