-----------------------------------------------------------------------
FWIW: I have now recovered, by renaming /var/lib/cassandra/commitlog/ and
recreated it as an empty directory, and Cassandra started OK. I still have the
old commitlog folder if it's interesting.

> 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.
