这里是Hadoop官网给出的该错误信息，即hadoop-auth没法编译通过，这里是直接把它们给出的错误信息粘贴过来了，如果你也遇到这个错误的话，可以找到hadoop目录下的hadoop-common-project/hadoop-auth文件夹下，可以看到在这下面有一个.pom文件，因为hadoop是用maven进行构建的，而pom文件是maven构建的必要文件，pom对于maven就相当于make对于Makefile,但是又不是完全相同的，因为pom文件中会给出项目构建所依赖的jar包，由maven自动进行依赖包的下载，从而实现对项目的构建。
这里的修改方法是在这个pom文件中的第58行加入
<artifactId>jetty-util</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty</artifactId>
当然可能因为下载的hadoop版本不同在所在行数上有所不同，具体的可以参见，https://issues.apache.org/jira/secure/attachment/12614482/HADOOP-10110.patch 这时hadoop官方提供的一个补丁，加入这些依赖之后，再进行构建，这里就没有问题了
