需要在maven的pom.xml dependency中添加hadoop-mapreduce-client-jobclient和hadoop-mapreduce-client-common的依賴

<dependency><groupId>org.apache.hadoop</groupId><artifactId>hadoop-mapreduce-client-common</artifactId><version>2.2.0</version></dependency><dependency><groupId>org.apache.hadoop</groupId><artifactId>hadoop-mapreduce-client-jobclient</artifactId><version>2.2.0</version></dependency>

pom.xml如下：
