Subject [GitHub] tez issue #33: TEZ-3998: support constructing DAG with concurrent edge
Date Sun, 21 Oct 2018 00:26:15 GMT
Github user yingdachen commented on the issue:

    https://github.com/apache/tez/pull/33
  
    Will be addressing the review comments in the next few days. 
    
    In addition, some more details will be provided for fault tolerance in terms of AM recovery.
I am thinking that to begin with, we will at least guarantee that the introduction of concurrent
edge would not interfere with normal AM recovery. 
    
    Design for fully functional recovery (for example, making the entire sub-graph connected
by concurrent edge a a failure region) will likely to follow after that, since there are quite
some details to polish.
