-----------------------------------------

             Summary: Batchlog replay fails with exception after a node is decommissioned
                 Key: CASSANDRA-10068
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10068
             Project: Cassandra
          Issue Type: Bug
            Reporter: Joel Knighton
         Attachments: n1.log, n2.log, n3.log, n4.log, n5.log

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.
