Jeff Zhang commented on TEZ-2311:
---------------------------------

[~lichangleo] [~jlowe], this context is not clear to me, have to admit that the current recovery code is fragile due to the evolving change of TEZ. I am doing a redesign of recovery, try to make it in 0.8, If you don't mind, I will move this jira to 0.8. Or if you think this is critical for you, could you please provide more context on that, app logs are helpful.
