Hi Hitesh,

If you think that MAPREDUCE-3796 will cover the test case of checking that 
yarn.nodemanager.resource.memory-mb   yarn.app.mapreduce.am.resource.mb and 
take appropriate actions accordingly then you can close it as dup of 
MAPREDUCE-3796.

Thanks,
Anil Gupta

 Key: MAPREDUCE-4508
 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4508
 Project: Hadoop Map/Reduce
  Issue Type: Bug
  Components: nodemanager, resourcemanager
Affects Versions: 2.0.0-alpha
 Environment: CentOs6.0, Hadoop2.0.0 Alpha
Reporter: Anil Gupta
  Labels: Map, Reduce, YARN

 Please refer to this discussion on the Hadoop Mailing list:
 http://comments.gmane.org/gmane.comp.jakarta.lucene.hadoop.user/33110
 Summary:
 I was running YARN(Hadoop2.0.0 Alpha) on a 8 datanode, 4 admin node 
 Hadoop/HBase cluster. My datanodes were only having 3.2GB of memory. So, i 
 configured the yarn.nodemanager.resource.memory-mb property in yarn-site.xml 
 to 1200. After setting the property if i run any Yarn Job then the 
 NodemManager wont be able to start any Map task since by default the 
 yarn.app.mapreduce.am.resource.mb property is set to 1500 MB in 
 mapred-site.xml. 
 Expected Behavior: NodeManager should give an error if 
 yarn.app.mapreduce.am.resource.mb = yarn.nodemanager.resource.memory-mb.
 Please let me know if more information is required.
