Review comment:
Do you think it would be better to return a Set<String> directly in
toNodeUuid(...), rather than return a list and then create a set from it? Its a
tiny optimisation but I don't think we really need the intermediate list - its
just used in the log message later and we can probably just use "nodes" rather
than nodeList in the log as it was before.
