The deactivate() on the spout will be called when the topology is
deactivated. Below is the output of storm deactivate help. This will
deactivate the whole topology and this can be from the Storm UI as well.
Does you topology have more than one Spout and are you looking to stop only
a subset of those Spouts?
$ storm help deactivate
Syntax: [storm deactivate topology-name]
Deactivates the specified topology's spouts.
