     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
