Bikas Saha commented on TEZ-2914:
---------------------------------
Attaching patch with the DAGScheduler approach with a unit and system test
using simulation.
DAGScheduler allows limits the number of attempts (per vertex) that can be
scheduled. This is done via a new base class - so all existing dag scheduler
get the functionality.
Removed unnecessary and unused dag scheduler events to reduce the AM event
dispatching load.
