> Failed replacements due to "Cannot replace token xxx which does not exist"

> Key: CASSANDRA-17896
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17896
> Project: Cassandra
> Issue Type: Bug

>
> Host replacements require host ID and token, however reporting of this info
> is typically blocked when the “status” field is missing. We should expose a
> system env (-D) param to advanced operators to have the ability to specify
> the replace_addresses_token to be used during host replacement in cases where
> Gossip gets into a bad state.
> Given this is inherently an unsafe / high risk manual intervention, we want
> to avoid promoting this to being a config param however Gossip quite often
> contorts into problematic split-brain states like this and having the ability
> to manually override things helps unstick host replacements that go
> straddled. Should update NEWS.txt at the very least and consider
> documentation as well
> This is an interim solution that'll be obviated by CEP-21, but is still
> useful on existing clusters.
