> During Blueprint deployments involving large cluster sizes (50 or more
> nodes), there is an intermittent failure that occurs in which a logical
> request never completes, since one or more expected host registrations do not
> complete, and so the request can not be fully resolved. This results in the
> UI showing that the logical request is pending, and the cluster fails to
> deploy to completion.
> This tends to happen under heavy load with large cluster sizes. This also
> tends to happen more frequently when hosts in the cluster are registered with
> the TopologyManager during the Blueprint configuration phase.
> This appears to be a concurrency problem with the TopologyManager.
> I'm working on a fix for this, and will be submitting a patch shortly.
