             Summary: Repair fuzz tests fail with paxos_variant: v2
                 Key: CASSANDRA-19042
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-19042
             Project: Cassandra
          Issue Type: Bug
          Components: Consistency/Repair, Feature/Lightweight Transactions, Test/fuzz
            Reporter: Branimir Lambov


Adding {{paxos_variant: v2}} to the test yaml causes all fuzz repair tests to fail with
{code}
java.lang.NullPointerException: null
	at org.apache.cassandra.gms.EndpointStateSerializer.serializedSize(EndpointState.java:337)
	at org.apache.cassandra.gms.EndpointStateSerializer.serializedSize(EndpointState.java:300)
	at org.apache.cassandra.service.paxos.cleanup.PaxosStartPrepareCleanup$RequestSerializer.serializedSize(PaxosStartPrepareCleanup.java:176)
	at org.apache.cassandra.service.paxos.cleanup.PaxosStartPrepareCleanup$RequestSerializer.serializedSize(PaxosStartPrepareCleanup.java:147)
	at org.apache.cassandra.net.Message$Serializer.payloadSize(Message.java:1067)
	at org.apache.cassandra.net.Message.payloadSize(Message.java:1114)
	at org.apache.cassandra.net.Message$Serializer.serializedSize(Message.java:750)
	at org.apache.cassandra.net.Message.serializedSize(Message.java:1094)
...
{code}

This happens for all three options of {{paxos_state_purging}} and both with and without {{storage_compatibility_mode: NONE}}.

Tests still fail if {{PaxosStartPrepareCleanup}} is changed to use {{EndpointState.nullableSerializer}}.
