--> 是Hbase没起来导致的，
--> 是hadoop集群没正常启动，datanode节点都没起来
--> 是datanode的集群ID与namenode的集群ID不一致，导致dn找不到集群
重复格式化导致datanode的clusterID和新的namenode的clusterID不一致，因此启动集群后只有namenode，没有datanode
解决办法：
1、停止集群并reboot重启（保证Hadoop的服务被杀死）namenode所在的节点
2、清理：
将hadoop的根目录中的data，logs全部删除(三台节点)：rm -rf $HADOOP_HOME/data $HADOOP_HOME/logs
将 /tmp下的内容全部删除：sudo rm -rf /tmp/*
用清理脚本实现一键删除三台节点：data，logs，tmp 目录下的内容。
3、重新格式化
hdfs namenode -format
最后，重新启动集群成功。
清理脚本
!/bin/bash
for host in hadoop102 hadoop103 hadoop104
do
ssh $host rm -rf $HADOOP_HOME/data $HADOOP_HOME/logs
ssh $host sudo rm -rf /tmp/*
done
