error decoding list of values for prefix:key

#./config/single-process-config.yaml as like https://github.com/kanuahs/cortex-demo/blob/master/docker-demo/cortex-configs/single-process-config.yaml

why does it reports the following error?

level=error ts=2019-12-26T10:03:54.746577132Z caller=client.go:275 msg="error decoding list of values for prefix:key" prefix=collectors/ key=collectors/ring err="proto: wrong wireType = 2 for field ReceivedAt"

I think the problem is that it's reusing the same consul used for the ring, and the WatchKey() done by the HA tracker clashes with the collectors/ring key.

A quick solution should be using a different prefix for the HA tracker, for example -distributor.ha-tracker.prefix=ha-tracker/.
