OK, I think I may have mis-understood your redaction, I thought it was a 
computer name, but I now think it is an OU path.
Either way, the computer already seems to exist in AD and as such, when 
the join tries to create the SPN, it fails because it already exists.

Now, you cannot have objects in AD with duplicate names, so try joining 
without the option, it may work and if it doesn't, then get the computer 
object in AD deleted and start again.
