Andy Tolbert commented on CASSANDRA-14655:
------------------------------------------
Thanks for providing the stack traces.
Ahh, I suppose that the cause of the NPE could just be that no {{Cluster}}
instance is provided in {{executeNet}} because it can't properly initialize
because of the {{system_virtual_schema}} issue.
In terms of {{system_virtual_schema}} being missing, I think the code that
loads/creates that keyspace is
[here|https://github.com/apache/cassandra/blob/06209037ea56b5a2a49615a99f1542d6ea1b2947/src/java/org/apache/cassandra/service/CassandraDaemon.java#L255-L256]
during the setup of {{CassandraDaemon}}. My guess is that if you add the
relevant code in CQLTester.requireNetwork, like [is
done|https://github.com/apache/cassandra/blob/207c80c1fd63dfbd8ca7e615ec8002ee8983c5d6/test/unit/org/apache/cassandra/cql3/CQLTester.java#L381]
for the system keyspace via {{SystemKeyspace.finishStartup()}} that will fix
this issue.
