Sunil G commented on YARN-7457: ------------------------------- Yes [~leftnoteasy]. In my YARN-7494 , I am already refactoring AppPlacementAllocator to pick from a factory and use a StringStringMap on ASC for scheduling env's alone. > Delay scheduling should be an individual policy instead of part of scheduler > implementation > ------------------------------------------------------------------------------------------- > > Key: YARN-7457 > URL: https://issues.apache.org/jira/browse/YARN-7457 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Wangda Tan > Assignee: Tao Yang > > Currently, different schedulers have slightly different delay scheduling > implementations. Ideally we should make delay scheduling independent from > scheduler implementation. Benefits of doing this: > 1) Applications can choose which delay scheduling policy to use, it could be > time-based / missed-opportunistic-based or whatever new delay scheduling > policy supported by the cluster. Now it is global config of scheduler. > 2) Make scheduler implementations simpler and reusable. > h2. {color:red}Running design doc: > https://docs.google.com/document/d/1rY-CJPLbGk3Xj_8sxre61y2YkHJFK8oqKOshro1ZY3A/edit#heading=h.xnzvh9nn283a{color} -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
