> 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
> - mapreduce.job.speculative.minimum-allowed-tasks
> - mapreduce.job.speculative.speculative-cap-total-tasks
