> Using released apache-cassandra-3.7.0, we have managed to get a node into a state where it won't start up. The exception is {{java.lang.AssertionError: We shouldn't have got there is the base row had no associated entry}} and it appears in ViewUpdateGenerator.computeLivenessInfoForEntry(ViewUpdateGenerator.java:455).
> I still have the offending node; what diags/data would be useful for diagnosis? I've attached the full cassandra.log. In summary, cassandra.log contains multiple instances of the following when replaying the commit log on startup, leading ultimately to failure to start up.
> {code}
> ERROR 15:24:17 Unknown exception caught while attempting to update MaterializedView! edison.scs_subscriber
