> Attempting to post a Blueprint with an invalid version number (Example, HDP Stack version "99.99") currently results in a "500 Server Error" being thrown back to the client, with no information on the cause of the error.  The ambari-server log shows that an internal exception is thrown, since the invalid stack error is not properly propagated back to the calling client. 
> The Blueprint processing code needs to throw a more reasonable error back to the caller, a "400" status error, with a meaningful error message when an invalid stack is referenced in a Blueprint.
> I'm working on a fix for this, and will be submitting a patch shortly.
