-----------------------------

             Summary: Container allocation issue in Leafqueue assignContainers()
                 Key: YARN-1631
                 URL: https://issues.apache.org/jira/browse/YARN-1631
             Project: Hadoop YARN
          Issue Type: Bug
          Components: scheduler
    Affects Versions: 2.2.0
         Environment: SuSe 11 Linux 
            Reporter: Sunil G


Application1 has a demand of 8GB[Map Task Size as 8GB] which is more than Node_1 can handle.
Node_1 has a size of 8GB and 2GB is used by Application1's AM.
Hence reservation happened for remaining 6GB in Node_1 by Application1.

A new job is submitted with 2GB AM size and 2GB task size with only 2 Maps to run.
Node_2 also has 8GB capability.

But Application2's AM cannot be launched in Node_2. And Application2 waits longer as only
2 Nodes are available in cluster.
