Muhammad Samir Khan created TEZ-3772: ----------------------------------------
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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
