    > I think the original blacklist mechanism and what @davies did is to avoid the resubmitted tasks running on the same executors/hosts, which means tasks should be failed beforehand, then the blacklist mechanism could take effect. But about the first submitted tasks, current implementation cannot avoid scheduling tasks on such "bad" executors. This is what this PR addresses about. The basic idea and algorithm is brought from MR, I think for Spark it also requires such feature.
    
    @jerryshao I see, thanks for the explanation. Are you still actively working on this? (Is it still "WIP") If so could you rebase to master?
