> When a validation error happens during cluster initialization, it is displayed as following:
> {noformat}
> [defaultNode]> cluster init --name=a 
> IGN-CMN-65535 Trace ID: c2f5b2a7-302e-4bc4-8417-0e57a8e3843c
> Got error response from node "defaultNode": Join request denied, reason: <ERROR MESSAGE>
> {noformat}
> A few potential improvements:
> # The CMN-65535 error should be avoided. This isn’t some unknown condition, this is absolutely normal scenario. This might not even be an “error” in terms of the user scenario - not sure if this warrants an error code, etc.
> # The error message is full of useless and misleading info.
> ## “Got error response” exposes the CLI/REST inner workings and protocol.
> ## “Join request denied” - whose join, where?
> The error message format must be updated to clearly state the problem.
