Fix it, then Ship it!




Overall, the patch looks fine, but I do have some concerns about whether this scenario should be treated as a failure condition, or if the exception mentioned in this review is a symptom of another bug.

Could you please add Sandor Magyari to this review, as he is another expert in this area of the code?  It would be good to get a second opinion on this, to make sure I'm interpreting this correctly.

Thanks.


ambari-server/src/main/java/org/apache/ambari/server/topology/ClusterTopologyImpl.java (line 236)
<https://reviews.apache.org/r/56627/#comment237573>

    I have some concerns about this change.
    
    While on the surface it would appear that this is the correct handling of this Blueprint deployment scenario, I'm a little concerned that this would preclude the following scenario:
    
    1. Blueprint is POST-ed with 4 host-groups
    2. Cluster Creation occurs, matching 3 hosts to 3 of the 4 host groups.
    3. At a later point, an Add Host REST call might be made, to add a new worker node based on the hostgroup that is not matched in the initial deployment.
    
    I might be mis-understanding the intent of the original code, so we should probably have another reviewing take a look as well to confirm.
