Jonathan Ellis commented on CASSANDRA-10238:
--------------------------------------------
This ticket is to fix the bug of part of the cluster having a different view of
the ring than other parts. If that is incomplete then let's reopen. (And say
so on the 2.0.17 vote thread.)
Moving nodes between racks causes other problems (data is not where it's
expected to be) but that's "working as designed" so changing the design is in
the other tickets (which won't go into 2.0.x).
> Consolidating racks violates the RF contract

> Key: CASSANDRA-10238
> 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.
