             Summary: Investigate if we need an atomic way to set both memory 
and CPU on Resource
                 Key: YARN-3991
                 URL: https://issues.apache.org/jira/browse/YARN-3991
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.7.1
            Reporter: Karthik Kambatla


While reviewing another patch, noticed that we have independent methods to set 
memory and CPU. 

Do we need another method to set them both atomically? Otherwise, would two 
threads trying to set both values lose any updates?
