-------------------------------
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.
