我使用以下语句使用此博客中的java文件创建了一个jar文件

javac -classpath /usr/local/hadoop/hadoop-core-1.0.3.jar -d /home/hduser/dir Dictionary.java

/usr/lib/jvm/jdk1.7.0_07/bin/jar cf Dictionary.jar /home/hduser/dir

现在我尝试通过命中和试验各种命令在hadoop中运行这个jar

1hduser@ubuntu:~$ /usr/local/hadoop/bin/hadoop jar Dictionary.jar

输出:

Warning: $HADOOP_HOME is deprecated.

RunJar jarFile [mainClass] args...  

2.hduser@ubuntu:~$ /usr/local/hadoop/bin/hadoop jar Dictionary.jar Dictionary

输出:

Warning: $HADOOP_HOME is deprecated.

Exception in thread "main" java.lang.ClassNotFoundException: Dictionary

我怎么能在hadoop中运行jar？根据我的程序需要,我有正确的DFS位置.
