Sam Tunnicliffe updated CASSANDRA-7765:
---------------------------------------
Component/s: Coordination
> Don't use strict endpoint selection for range movements where RF == node count
> ------------------------------------------------------------------------------
>
> Key: CASSANDRA-7765
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7765
> Project: Cassandra
> Issue Type: Bug
> Components: Coordination
> Reporter: Sam Tunnicliffe
> Assignee: Sam Tunnicliffe
> Priority: Minor
> Fix For: 2.1.0
>
> Attachments: 7765.txt
>
>
> Post CASSANDRA-2434, we should skip strict endpoint selection for ranges
> where RF == the number of nodes in the cluster otherwise we hit the following
> assertion in {{RangeStreamer.getAllRangesWithStrictSourcesFor}}
> {code}
> if (oldEndpoints.size() == strat.getReplicationFactor())
> {
> oldEndpoints.removeAll(newEndpoints);
> assert oldEndpoints.size() == 1 : "Expected 1 endpoint but found " +
> oldEndpoints.size();
> }
> {code}
> I think this is a fairly niche case, plus there's a workaround in the
> {{-Dcassandra.consistent.rangemovement=false}} option.
