title: How to get the scheduler of an already finished job in Yarn Hadoop?
body: <p>So I'm in this situation, where I'm modifying the mapred-site.xml and specific configuration files of different schedulers for Hadoop, and I just want to make sure that the modifications I have made to the default scheduler(FIFO), has actually taken place. </p>
  
  <p>How can I check the scheduler applied to a job or a queue of jobs already submitted to hadoop using job id ?</p>
  
  <p>Sorry if this doesn't make that much sense, but I've looked around quite extensively to wrap my head around it, and read many documentations, and yet I still cannot seem to find this fundamental piece of information. </p>
  
  <p>I'm simply trying the word count as a job, changing scheduler settings in mapped-site.xml and yarn-site.xml.
  For instance I'm changing property "yarn.resourcemanager.scheduler.class" to "org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler" based on this link : <a href="https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/CapacityScheduler.html#Setting_up_ResourceManager_to_use_CapacityScheduler" rel="nofollow noreferrer">see this</a></p>
  
  <p>I'm also moving appropriate jar files specific to the schedulers to the correct directory.</p>
  
  <p>For your reference, I'm using the "yarn" runtime mode, and Cloudera and Hadoop 2.</p>
  
  <p>Thanks a ton for your help</p>
