Hitesh Shah commented on TEZ-853:
---------------------------------
Comments:
- Do TaskImpl and VertexImpl write counters to recovery but they are not used
when restoring state? Should the counters be written or recovered from task
attempts? If the latter, then we should not write them.
- DAGImpl::restoreFromEvent does not seem to restore counters
- in a scenario where the dag finished is logged and all other events are
dropped, I assume counters will be needed?
> Support counters recovery
