–> It is caused by Hbase not being up.
–> it’s because hadoop cluster is not started properly and datanode nodes are not up
–> The cluster ID of the datanode is not the same as the cluster ID of the namenode, so dn can’t find the cluster

Duplicate formatting causes the clusterID of the datanode and the clusterID of the new namenode to be inconsistent, so when the cluster is started there is only the namenode, not the datanode

Workaround.
1, stop the cluster and reboot to restart (to ensure that Hadoop’s services are killed) the node where the namenode is located
2. Clean up.
Delete all data and logs in the root directory of hadoop (three nodes): rm -rf $HADOOP_HOME/data $HADOOP_HOME/logs
Delete all contents under /tmp: sudo rm -rf /tmp/*
Use the cleanup script to delete the contents of the three nodes: data, logs, and tmp directories in one click.
3, reformat
hdfs namenode -format
Finally, restart the cluster successfully.


Cleanup script
!/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
