## Proposed changes
At present, the version of separation of storage and computation version and
the version of computational storage cannot be converted to each other. But if
the user insists on mixing the two, there is no way to avoid it at the code
level. The following are possible scenarios that may occur:
Case | The node has been in Cloud cluster before | The node has been in
Local cluster before | The node never been in any cluster
-- | -- | -- | --
add BE to local cluster | Add successfully, but error `invalid cluster id.
ignore. ` will be occurred. No negative impact on the original two clusters. |
Add successfully, but error `invalid cluster id. ignore. ` will be occurred.
No negative impact on the original two clusters. | If cloud configuration is
not added, it can work normally<br />If cloud configuration has been added, it
will resulting in the inability to start normally
add FE to local cluster | Add successfully, but error `Socket is closed by
peer. ` will be occurred. No negative impact on the original two clusters. |

| Case |
|
| --------------------------------------------- |
------------------------------------------------------------ |
| BE in Local cluster add cloud config items | Hang up
|
| FE in Local cluster add cloud config items | Hang up
|
| BE in Cloud cluster remove cloud config items | run successfully, but
error occur when do querying or inserting |
| FE in Cloud cluster remove cloud config items | service down
|
In this PR, I will check Doris' deployment mode. If the deployment mode is
modified later, the service will be down and a clear error message will be
given.
