> this issue to fix two problems：
>   1. add new two test case. test CartesianProduct join and BroadcastNestedLoop join. We understand the effect of CodeGen on them. and through these two test cases, we can know Per Row (NS), is much more delayed than our previous hash join.
>   2.similar 'logical.Join', is not right, to be consistent in SparkStrategies.scala. fix to remove package name.
