执行命令时

hadoop jar /home/edureka/Desktop/invertedindex.jar hdfs:/hdfs/inverted  hdfs:/hdfs/invertedout

我得到下面的错误
有人能帮我修改代码吗
线程“main”java.lang.classnotfoundexception中出现异常：hdfs:.hdfs.inverted at java.net.urlclassloader$1.run（urlclassloader。java:366)在java.net.urlclassloader$1.run（urlclassloader。java:355)位于java.net.urlclassloader.findclass（urlclassloader）的java.security.accesscontroller.doprivileged（本机方法）。java:354)在java.lang.classloader.loadclass（类加载器。java:425)在java.lang.classloader.loadclass（classloader。java:358)在java.lang.class.forname0（本机方法）在java.lang.class.forname（类。java:270)在org.apache.hadoop.util.runjar.main（runjar。java:205)
我尝试了所有的先决条件，但仍然面临这个问题。 enter code here 代码如下：
