>
> Currently when we save host-overrides configuration, we have to do PUT of the
> delta on each host.
> This is problematic if admin provides an exception to 100 hosts. This will
> require 100 PUT calls which is expensive. There is a bulk update mechanism,
> but that requires the same content for all 100 hosts. This will not be the
> case if any hosts have other properties that are overridden.
> To save on network calls, we have to make one PUT call via the new API
> provided by AMBARI-1844.
