Thank you for the quick rebase. I have two questions.
* ```tajo-jdbc``` has a dependency on ```tajo-cluster-tests```, but
```tajo-cluster-tests```'s target is 1.8. Is it ok?
* Both ```tajo-client``` and ```tajo-jdbc``` have some nested dependencies.
For example, ```tajo-client``` has a dependency on ```tajo-rpc-protobuf```, and
which in turn it has a dependency on ```tajo-rpc-common```. In this case, I
wonder that it is ok if ```tajo-rpc-common```'s target is still 1.8.
