--------------------------------
Hi, Fangjun, I see this issue has been inactive for a while. Does it matter if
I take a shot on this?
If it is OK, I will assign it to me and submit a pull request for updating the
doc descriptions for TOPOLOGY_ACKER_EXECUTORS. Please feel free to pose if you
have a different opinion.
> config topology.acker.executors default value is null and then should not
> start acker bolts
