Jonathan Eagles commented on TEZ-1467:
--------------------------------------
It appears the the console DAG progress (computed in DAGClientRPCImpl) is
reporting percentage of tasks complete vs RM UI (computed in DAGImpl) is
reporting the average vertex progress. The client can and does make calls to
the AM to get the individual vertex status if the user requests, but it may be
costly to keep this number perfectly in sync for large jobs. [~sseth], do you
want to weigh in on this?
> Tez job "actual" status is miss-reported between RM UI and Console
