Question

我正在使用hadoop版本2.5.0。
在此行上运行mapreduce作业时获取此异常

boolean b = job.waitForCompletion(true);

更新
我的问题是hadoop需要从guava16.0中删除的LimitInputStream类，并且是guava14.0。在添加org.springframework.boot时：spring-boot-gradle-plugin：1.2.7.RELEASE 我收到了这个错误。我该如何解决这个问题

你必须强制番石榴版本为14.0

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
            <version>14.0</version>
        </dependency>
    </dependencies>
</dependencyManagement>

java.lang.reflect.InvocationTargetException java.lang.NoClassDefFoundError：com / google / common / io / LimitInputStream
