hadoop2.0(cdh4) fs client错误"java.io.IOException: No FileSystem for scheme: hdfe"

启动dfs client时候报错：“java.io.IOException: No FileSystem for scheme: hdfs"”

出现这个错误是因为缺少hadoop-hdfs jar包，在项目中进行如下依赖配置即可，两个都不能少，下面是cloudera maven配置

<dependency>
			<groupId>org.apache.hadoop</groupId>
			<artifactId>hadoop-common</artifactId>
			<version>2.0.0-cdh4.4.0</version>
			<exclusions>
				<exclusion>
					<artifactId>jdk.tools</artifactId>
					<groupId>jdk.tools</groupId>
				</exclusion>
			</exclusions>
		</dependency>
