Cause Analysis:
The reason for this problem may be that the metadata of your HBase in zookeeper has not been completely deleted. I have installed HBase before, and then recently reinstalled other versions, so the metadata of the previous version of HBase in zookeeper has not been completely deleted.
solution:
The client connected to zookeeper can delete the original HBase metadata
bin/zkCli.sh
Then use the following command to delete the metadata information of HBase:
deleteall /hbase
Then restart the HBase service. Note: When deleting metadata, the HBase service must be stopped.
