Jungtaek Lim commented on STORM-587:
------------------------------------
Actually it is already documented from Trident Spout page(stream txid should be
unique to whole cluster), so it may be better to check first that it was
intended or just missed spot.
> trident transactional state in zk should be namespaced with topology id

> Currently when a trident transaction spout is initialized it creates a node
> in zk under /transactional with the spout name as the node's name. This is
> pretty dangerous as any other topology can be submitted with same spout name
> and now these 2 spouts will be overwriting each other's states. I believe it
> is better to namespace this with topologyId just like all other zk entries
> under /storm.
