Maven引入Hadoop依赖报错：Missing artifact jdk.tools:jdk.tools:jar:1.6

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

原因是缺少tools.jar的依赖，tools.jar在jdk的安装目录中提供了，所以改成如下形式解决此问题：

		<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>
		<dependency>
			<groupId>jdk.tools</groupId>
			<artifactId>jdk.tools</artifactId>
			<version>1.6</version>
			<scope>system</scope>
			<systemPath>${JAVA_HOME}/lib/tools.jar</systemPath>
		</dependency>
