[jira] [Created] (TEZ-1700) Replace containerId from TaskLocationHint with [TaskIndex+Vertex] based affinity

Bikas Saha created TEZ-1700:
-------------------------------

             Summary: Replace containerId from TaskLocationHint with [TaskIndex+Vertex] based affinity
                 Key: TEZ-1700
                 URL: https://issues.apache.org/jira/browse/TEZ-1700
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Bikas Saha


Today 1-1 dependencies are affinitized by creating a task location hint with the producer task container id. It can be created by affinitizing to the producer task-index+vertexname combination instead and internally Tez can map it to the container. This also allows this dependency to be specified before the container is assigned. This allows the dependency to be generic.
