Kuhu Shukla commented on TEZ-3952:
----------------------------------
Thanks for the update!
I don't think the patch compiles [~nishantdash]. Could you take the v1 version
of the patch and modify that so that all file changes reflect?
Thanks a lot!

> Many of the settings for Tez task speculation are hardcoded and should
> instead be configurable. For example, there's no equivalent config settings
> for the following MapReduce settings:
> - mapreduce.job.speculative.speculative-cap-running-tasks
> - mapreduce.job.speculative.retry-after-no-speculate
> - mapreduce.job.speculative.retry-after-speculate
