Major Description
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
