Slave nodes not in Yarn ResourceManager

Question

I\'ve set up a 3 node Apache Hadoop cluster. On master node, I can see

[hadoop-conf]$ jps
16856 DataNode
17051 SecondaryNameNode
16701 NameNode
21601 Resour         


        

Answer 1

I added the following to yarn-site.xml on all nodes including NameNode (assuming it will be used as well):

  
  yarn.resourcemanager.resource-tracker.address  
  {Enter NameNode IP Address}:8025  
  
  
  yarn.resourcemanager.scheduler.address  
  {Enter NameNode IP Address}:8030  
  
  
  yarn.resourcemanager.address  
  {Enter NameNode IP Address}:8040
