使用 ant 构建 Hadoop 1.2.1 核心 jar - 失败 [英] Building Hadoop 1.2.1 core jar using ant - Failed

问题描述

我需要对 Hadoop 中的 map 类和 reduce 类进行一些修改，因此，我一直在尝试使用源文件中的 ant 来编译 Hadoop 1.2.1 jar 文件，但总是出现以下错误:

I need to make some modifications to the map class and reduce class from Hadoop, so, I have been trying to compile Hadoop 1.2.1 jar files using ant from the source files, but I always get the following error:

有人知道可能是什么问题吗?或者知道如何使用 ant 创建 jar 文件?

Does anybody know what could be the problem? or knows how to create the jar files using ant?

谢谢
