Could you put the `<>` characters back at the end of the LinkedHashSet?
> Generate trident bolt ids with sorted group names

>
> In genBoltId() method of TridentTopology, groups are stored in HashSet.
> So everytime I submit my trident topology, I get different id for my
> component.
> For example, this time my bolt ids are (b-0-abc, b-1-def), next time they are
> (b-1-abc, b-0-def).
> It makes harder for users to track their metrics, and the bolt names in UI
> are changing too.
