Jeff Zhang commented on TEZ-1069:
---------------------------------
After more thinking, it would change a lot on VM. So the next step I will first
put all these stuff in vertex and move to VM if necessary later.
> Support ability to re-size a task attempt when previous attempts fail due to
> resource constraints

>
> Consider a case where attempts for the final stage in a long DAG fails due to
> out of memory. In such a scenario, the framework ( or via the base vertex
> manager ) should be able to change the task specifications on the fly to
> trigger a re-run with modified specs.
> Changes could be both java opts changes as well as container resource
> requirements.
