[jira] [Created] (YARN-340) Rename DefaultResourceCalculator

Eli Collins created YARN-340:
--------------------------------

             Summary: Rename DefaultResourceCalculator
                 Key: YARN-340
                 URL: https://issues.apache.org/jira/browse/YARN-340
             Project: Hadoop YARN
          Issue Type: Improvement
    Affects Versions: 2.0.0-alpha
            Reporter: Eli Collins
            Priority: Minor


Let's rename DefaultResourceCalculator to something like MemoryResourceCalculator or SingleResourceCalculator. The default resource calculator is the one specified by yarn.scheduler.capacity.resource-calculator in yarn-default.xml (which may change).  We can do this compatibly now since YARN-2 hasn't been released yet, but changing this later will be a pain if we ever make a different resource calculator the default (or DefaultResourceCalculator won't actually be the default, which is weird).
