[jira] [Created] (TEZ-1053) Refactor: Pass TaskLocationHint directly to the Scheduling logic

             Summary: Refactor: Pass TaskLocationHint directly to the Scheduling logic
                 Key: TEZ-1053
                 URL: https://issues.apache.org/jira/browse/TEZ-1053
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Bikas Saha
            Assignee: Bikas Saha


Currently, the location hint is resolved and translated to hosts and relaxed to racks directly in the TaskAttemptImpl code. The AMRMClient already does that and so we are duplicating the name resolution and relaxation of host->rack. Also, as the information in TaskLocationHint evolves further, eg. support for container locality, then its better to leave the bindings as late as possible.
