Russ Hatch commented on CASSANDRA-10238:
----------------------------------------
Was able to repro with a [simple
dtest|https://github.com/riptano/cassandra-dtest/pull/545/files]. Happening on
2.1 head, 3.0 head, 3.0.0-beta2, and trunk.
Happens without DTCS, no large data write necessary.
> 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: Russ Hatch
>
> 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.
