Hello!
Troubleshooting guideline
Stop the HBase service, restore the table description information from another normal cluster and restart the HBase service.
Operation procedure
1. Stop the HBase service.

2. Run the following command to go to the installation directory on the client, for example, /opt/client:
cd /opt/client
3. Run the source bigdata_env command to configure environment variables.
4. If the cluster uses the security version, you need to perform security authentication.
kinit hbase
5. Enter the correct password as prompted.
[root@10-10-10-11 client]# source bigdata_env #Configure environment variables.
[root@10-10-10-11 client]# kinit hbase #Configure kinit authentication.
Password for hbase@HADOOP.COM:
6. Upload the .tableinfo.0000000001 table description information to /hbase/data/hbase/namespace/.tabledesc/.
[root@10-10-10-11 client] # hdfs dfs -put .tableinfo.0000000001 /hbase/data/hbase/namespace/.tabledesc/
7. Change the permission to hbase supergroup.
[root@10-10-10-11 client] # hdfs dfs -chown hbase:supergroup /hbase/data/hbase/namespace/.tableinfo.0000000001
8. Restart the HBase service to clear the table information cached in the HBase memory.
Verification
1. Perform the hbase hbck check:
hbase hbck hbase:namespace
[root@10-10-10-11 client]# hbase hbck hbase:namespace #Check the status … …
