> This came up in discussion of CASSANDRA-11687. {{nodetool rebuild}} was failing in a dtest. [~pauloricardomg] explained:
> bq. before [CASSANDRA-11848] the local node could be considered a source, while now sources are restricted only to dc2, so since {{system_auth}} uses {{SimpleStrategy}} depending on the token arrangement there could or not be sources from dc2. Fix is to either use {{-Dcassandra.consistent.rangemovement=false}} or update {{system_auth}} to use {{NetworkTopologyStrategy}} with 2 dcs..
> This is, at the very least, a UX bug. When {{rebuild}} fails, it fails with
> {code}
> nodetool: Unable to find sufficient sources for streaming range (-3287869951390391138,-1624006824486474209] in keyspace system_auth with RF=1.If you want to ignore this, consider using system property -Dcassandra.consistent.rangemovement=false.
> {code}
> which suggests that a user should give up consistency guarantees when it's not necessary.
