> This issue is reproducible through a Jepsen test of materialized views that
> crashes and decommissions nodes throughout the test.
> At the conclusion of the test, a batchlog replay is initiated through
> nodetool and hits the following assertion due to a missing host ID:
> https://github.com/apache/cassandra/blob/3413e557b95d9448b0311954e9b4f53eaf4758cd/src/java/org/apache/cassandra/service/StorageProxy.java#L1197
> A nodetool status on the node with failed batchlog replay shows the following
> entry for the decommissioned node:
> DN 10.0.0.5 ? 256 ? null
> rack1
> On the unaffected nodes, there is no entry for the decommissioned node as
> expected.
> There are occasional hits of the same assertions for logs in other nodes; it
> looks like the issue might occasionally resolve itself, but one node seems to
> have the errant null entry indefinitely.
> In logs for the nodes, this possibly unrelated exception also appears:
> java.lang.RuntimeException: Trying to get the view natural endpoint on a
> non-data replica
> at
> org.apache.cassandra.db.view.MaterializedViewUtils.getViewNaturalEndpoint(MaterializedViewUtils.java:91)
> ~[apache-cassandra-3.0.0-alpha1-SNAPSHOT.jar:3.0.0-alpha1-SNAPSHOT]
> I have a running cluster with the issue on my machine; it is also repeatable.
> Nothing stands out in the logs of the decommissioned node (n4) for me. The
> logs of each node in the cluster are attached.
