Subject [GitHub] tez issue #33: TEZ-3998: support constructing DAG with concurrent edge
Date Fri, 19 Oct 2018 20:44:46 GMT
Github user jteagles commented on the issue:

    @yingdachen, a few other considerations. 1)Normally, a feature like this could be a candidate
for feature branch. Do to the low risk interaction with Systems and backwards compatible API,
I think we could allow develop in trunk. It may cause some coordinating with ongoing 0.10
build to prevent delay of that release line. 2) Please provide some input on fault tolerance
of AM and attempt in the presence of Concurrent Edges. Specifically, we will want to provide
fault tolerance guarantees and possible interactions with AM recovery and assign component
responsibilities and interactions where needed.
