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

             Summary: Allow specifying locality constraints in YARN driver configuration
                 Key: REEF-1048
                 URL: https://issues.apache.org/jira/browse/REEF-1048
             Project: REEF
          Issue Type: Improvement
          Components: REEF-Runtime-YARN
            Reporter: Tobin Baker
            Assignee: Tobin Baker
            Priority: Minor


In some scenarios it would be useful to specify node/rack locality for the Driver container
(YARN ApplicationMaster). One example is a cloud computing cluster where each "worker" instance
is provisioned with just enough memory to run a single Task container, but not an additional
Driver container. YARN allows you to do this with node labels (presentation: http://www.slideshare.net/Hadoop_Summit/node-labels-in-yarn-49792443),
but this isn't exposed in YARN Driver configuration. If we add node/rack parameters to {{org.apache.reef.runtime.yarn.driver.
YarnDriverConfiguration}}, we should be able to implement this functionality using node labels.
