topology.ackers set to 0, still acking in downstream bolts?

[John Yost]

Hi Everyone,

I have a topology that consists of a KafkaSpout and three downstream bolts.

I turned off acking by setting topology.acker.executors to 0. It's my
understanding that I should only have acking in the KafkaSpout. However, I
see acking in all of my downstream bolts as well. Any ideas as to why?

Thanks
