Eclipse puts Hadoop projects in the cluster

1, add the configuration file to the project source directory (SRC)

 
   
  

  
    
   
<configuration>
  
    
   
<property>
  
    
   
<name>mapreduce.framework.name</name>
  
    
   
<value>yarn</value>
  
    
   
</property>
  
    
   
</configuration>
 
   
  

Read the contents of the configuration file so that the project knows to submit to the cluster to run
2, package the project into the Project source directory (SRC) 3, add a sentence in Java code

 
   
  

  
    
   
Configuration conf = new Configuration();
  
    
   
conf.set("mapreduce.job.jar", "wc.jar");
 
   
  

Note: These are intended to allow the cluster to find the jar package to run
