> This issue is reproducible through a Jepsen test of materialized views that
> crashes and decommissions nodes throughout the test.
> In a 5 node cluster, if a node crashes at a certain point (unknown) during
> the decommission of a different node, it may start with a null entry for the
> decommissioned node like so:
> DN 10.0.0.5 ? 256 ? null rack1
> This entry does not get updated/cleared by gossip. This entry is removed upon
> a restart of the affected node.
> This issue is further detailed in ticket
> [10068|https://issues.apache.org/jira/browse/CASSANDRA-10068].
