Maven引入Hadoop依賴報錯：Missing artifact jdk.tools:jdk.tools:jar:1.6

原因是缺少tools.jar的依賴，tools.jar在jdk的安裝目錄中提供了，所以改成如下形式解決此問題：
添加依賴

<dependency>  
    <groupId>org.apache.hadoop</groupId>  
    <artifactId>hadoop-mapreduce-client-core</artifactId>  
    <version>2.4.0</version
 
>  
    <exclusions>  
        <exclusion>  
            <groupId>jdk.tools</groupId>  
            <artifactId>jdk.tools</artifactId>  
        </exclusion>  
    </exclusions>  
</dependency>
