----------------------------------------
Summary: Allow slowstart for small jobs to be treated differently
Key: TEZ-3772
URL: https://issues.apache.org/jira/browse/TEZ-3772
Project: Apache Tez
Issue Type: Improvement
Reporter: Muhammad Samir Khan
Assignee: Muhammad Samir Khan
If there are a small number of reduces (configurable), then having a different
threshold can benefit. Performance of jobs with a small number of reduce tasks
can benefit significantly. Yes, the job could specify slowstart as 0.0 instead
of the default, but that requires job owners to do something. It would be
better if the defaults did something more optimal for both large and small jobs.
