>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10238
>             Project: Cassandra
>          Issue Type: Bug
>          Components: Core
>            Reporter: Brandon Williams
>            Assignee: Stefania
>            Priority: Critical
>             Fix For: 2.0.17, 3.0.0 rc1, 2.1.10, 2.2.2
>
>
> I have only tested this on 2.0 so far, but I suspect it will affect multiple versions.
> Repro:
> * create a datacenter with rf>1
> * create more than one rack in this datacenter
> * consolidate these racks into 1
> * getendpoints will reveal the RF in practice is 1, even though other tools will report
the original RF that was set
> Restarting Cassandra will resolve this.
