问题描述

假设我们有一张桌子：

Owner   | Pets
------------------------------
Jack    | "dog, cat, crocodile" 
Mary    | "bear, pig"

我想得到的结果是：

Owner   | Pets
------------------------------
Jack    | "dog"
Jack    | "cat"
Jack    | "crocodile" 
Mary    | "bear"
Mary    | "pig"

我通过谷歌搜索找到了类似问题的一些解决方案，但是Impala SQL不提供任何解决方案
