The cluster name is overwritten by DM. How can I view the cluster in this situation?
TiDB can be used normally, but the cluster cannot be operated through the tiup command.
It seems like the cluster component cannot be found. In other words, is the cluster command not found?
Yes, it seems to be overwritten.
Check if it’s a path issue or if it’s simply not in this location.
The default value of tidb_dml_batch_size is 2000. You can adjust this parameter according to your actual situation.
There are commands, which is a bit confusing. 
It seems that the environment variables are messed up. Try using the absolute path.
It’s a rather strange issue, check the environment variables.
Using absolute paths to check both DM and the cluster are normal, it should be caused by environment variables.
It’s best not to use the same names for DM and cluster, especially on mixed-use machines.
