Jeff Zhang commented on TEZ-2581:
---------------------------------
bq. Does the client transition to using ATS for completed DAGs? If yes, then
perhaps we dont need this since the client will transition to using the ATS.
getDAGStatus & getVertexStatus is RPC call, it doesn't matter with ATS.
bq. In this same context, what happens to ATS data?
Yes, this is known issue that there may be inconsistency between the ATS data
and recovery data. The processing recovery events and ATS events are now in
different threads, currently have no good solution for that.
