> The new Blueprint dynamic provisioning mechanism, added in Ambari 2.1.0, does
> not log much useful information when handling the setup of a cluster.
> This is particularly problematic in large cluster deployments that use the
> predicate syntax in the cluster creation template.
> Logging should be added to the TopologyManager and other classes in this area
> of Blueprints in order to facilitate simpler debugging of problems,
> particularly problems that occur in large-scale, high-concurrency
> environments.
> I'm working on a fix for this, and will be submitting a patch shortly.
