>             Project: Cassandra
>          Issue Type: Bug

> When the {{PER PARTITION LIMIT}} is greater than the page size the limit is not respected
for single or multi partitions queries.
> The problem can be reproduced using the java driver with the following code:
> {code}
>         session = cluster.connect();
>         session.execute("CREATE KEYSPACE IF NOT EXISTS test WITH REPLICATION = {'class'
: 'SimpleStrategy', 'replication_factor' : '1'}");
>         session.execute("USE test");
>         session.execute("DROP TABLE IF EXISTS test");
>         session.execute("CREATE TABLE IF NOT EXISTS test (a int, b int, c int, PRIMARY
KEY(a, b))");
>         PreparedStatement prepare = session.prepare("INSERT INTO test (a, b, c) VALUES
(?, ?, ?);");
>         for (int i = 0; i < 5; i++)
>             for (int j = 0; j < 10; j++)
>                 session.execute(prepare.bind(i, j, i + j));
>         ResultSet rs = session.execute(session.newSimpleStatement("SELECT * FROM test
WHERE a = 1 PER PARTITION LIMIT 3")
>                                               .setFetchSize(2));
>         for (Row row : rs)
>         {
>             System.out.println(row);
>         }
> {code}
