ArcGIS Tools for hadoop 使用

ArcGIS Tools for hadoop，简称ATH（下同）由三个组件组成：几何计算包，空间计算包，ArcGIS桌面工具。

我们这篇文档主要关注前两个。几何计算是一个独立的jar包，空间计算包是一个Hive的扩展，因此需要Hive环境才能运行。

设置环境

在此处下载样例包，解压后，samples目录中为几个示例，我们此处将使用point-in-polygon-aggregation-hive。

单元测试测什么？

单元测试中，最常见的错误是追溯被测试组件的所有依赖，并尝试将这些依赖实例化。一不小心就将单元测试做成了集成测试。

有依赖关系的测试
