[jira] [Created] (YARN-450) Define value for * in the scheduling protocol

Bikas Saha created YARN-450:
-------------------------------

             Summary: Define value for * in the scheduling protocol
                 Key: YARN-450
                 URL: https://issues.apache.org/jira/browse/YARN-450
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Bikas Saha
            Assignee: Zhijie Shen


The ResourceRequest has a string field to specify node/rack locations. For the cross-rack/cluster-wide location (ie when there is no locality constraint) the "*" string is used everywhere. However, its not defined anywhere and each piece of code either defines a local constant or uses the string literal. Defining "*" in the protocol and removing other local references from the code base will be good.
