> When querying using CQL statements (not prepared) the message type is QueryMessage and
the code in https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/transport/messages/QueryMessage.java#L101
is as follows:
> {code:java}
>             if (state.traceNextQuery())
>             {
>                 state.createTracingSession();
>                 ImmutableMap.Builder<String, String> builder = ImmutableMap.builder();
> {code}
> {{state.createTracingSession();}} should probably be {{state.createTracingSession(getCustomPayload());}}.
At least that fixes the problem for me.
> This also raises the question whether some other parts of the code should pass the custom
payload as well (I'm not the right person to analyze this):
> {code}
> $ ag createTracingSession
> src/java/org/apache/cassandra/service/QueryState.java
> 80:    public void createTracingSession()
> 82:        createTracingSession(Collections.EMPTY_MAP);
> 85:    public void createTracingSession(Map<String,ByteBuffer> customPayload)
> src/java/org/apache/cassandra/thrift/CassandraServer.java
> 2528:            state().getQueryState().createTracingSession();
> src/java/org/apache/cassandra/transport/messages/BatchMessage.java
> 163:                state.createTracingSession();
> src/java/org/apache/cassandra/transport/messages/ExecuteMessage.java
> 114:                state.createTracingSession(getCustomPayload());
> src/java/org/apache/cassandra/transport/messages/QueryMessage.java
> 101:                state.createTracingSession();
> src/java/org/apache/cassandra/transport/messages/PrepareMessage.java
> 74:                state.createTracingSession();
> {code}
> This is not marked as `minor` as the CASSANDRA-11706 was because this cannot be fixed
by the tracing plugin.
