---------------------------------------------
Looks good to me. Nice catch.
> Distributed tests can return ordering columns that have not been selected

> Key: CASSANDRA-18892
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18892
> Project: Cassandra
> Issue Type: Bug
> Components: Test/dtest/java
> Reporter: Mike Adamson
> Assignee: Mike Adamson
> Priority: Normal
>
> The following test fails
> {code:java}
> @Test
> public void incorrectClusteringColumnTest() throws IOException
> {
> try (Cluster cluster = init(Cluster.build(1).start()))
> {
> cluster.schemaChange(withKeyspace("CREATE TABLE %s.t (k int, c int, v
> int, primary key(k, c))"));
> cluster.coordinator(1).execute(withKeyspace("INSERT INTO %s.t (k, c,
> v) VALUES (0, 1, 2)"), ConsistencyLevel.QUORUM);
> String query = withKeyspace("SELECT v FROM %s.t WHERE k IN (0, 1)
> ORDER BY c LIMIT 10");
> assertRows(cluster.coordinator(1).execute(query,
> ConsistencyLevel.ONE), row(2));
> }
> }
> {code}
> The query is returning the clustering column c as well as the regular column
> v.
> The reason for the extra column being returned is that the RowUtil is using
> ResultMessage.Rows.result.metadata.names instead on
> ResultMessage.Rows.result.metadata.requestNames(). This last method removes
> columns that have not been requested.
