>    Affects Versions: 2.4.0
>            Reporter: Laszlo Puskas
>            Assignee: Laszlo Puskas

>
> When a cluster is created using blueprints it is possible to pass 
> configuration in the cluster creation template (that is posted after the 
> blueprint isent in)
> On cluster provisioning configurations are validated and if errors are found 
> the cluster provisioning is interrupted. As the configuration validation is 
> done after the cluster resources are persisted it's not possible to resend 
> the (possibly corrected) cluster template and restart the cluster 
> provisioning.
> Solution:
> Perform the configuration type validation before the cluster resources are 
> persisted.
