Waiting for the full document, it seems that many issues are due to the lack of document. Such as [issue 153](https://github.com/airbnb/airpal/issues/153),[issue 149](https://github.com/airbnb/airpal/issues/149) and [issue 140](https://github.com/airbnb/airpal/issues/140).

It did work as @picharras said. I test it with Presto 0.103

我已经修改成“准备新分区”了
