    Description

      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.
