Hitesh Shah updated TEZ-1069:
-----------------------------
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.
