> 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].
