我正在尝试构建hadoop，在hadoop common上运行surefire测试时遇到以下一组测试失败：
与符号链接有关的故障
与压缩有关的故障
我查看了目录的权限，它们似乎很好：

drwxr-xr-x  2 tom tom  4096 Jul 17 10:51

我不知道该怎么处理压缩问题。所以我希望它与象征性的联系有关。但我真的需要有压缩工作。我确实在禁用测试的情况下运行了构建，但是当尝试解压缩一个文件时，其中有很多错误，正如测试已经指出的那样。
设置：

Power8
Ubuntu 14.04
Hadoop 2.4.1

生成命令：

mvn package -Pdist,native -Dtar

失败测试：
