See Code:
https://github.com/caofangkun/apache-storm/blob/master/storm-core/src/clj/backtype/storm/daemon/common.clj#L315
Config "topology.acker.executors" default value is null
then acker executors will be same as "topology.workers"
$ storm jar storm-starter-0.10.0-SNAPSHOT.jar storm.starter.ExclamationTopology 
ExclamationTopology
Executors show up as 18 executors = 10(word) + 3(exclaim1) + 2(exclaim2) + 
3(acker bolt)
But the 3 acker bolt executors will not be used.
