Subject [jira] [Commented] (YARN-5542) Enhancements to opportunistic containers scheduling
Date Wed, 29 Nov 2017 04:06:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-5542?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16270098#comment-16270098

Konstantinos Karanasos commented on YARN-5542:
----------------------------------------------

Hi [~cheersyang], the core scheduling of opportunistic containers (YARN-5220 for centralized
scheduling and YARN-2877 for distributed scheduling) is done and is part of Hadoop 2.9 and
3.0 releases.
However, the JIRAs here are not done and we are not working on them currently, although I
believe they could lead to significant improvements in opportunistic container scheduling.
Would you be interested in working in one/some of them?

> This JIRA groups all efforts related to the scheduling of opportunistic containers. 
> It includes the scheduling of opportunistic container through the central RM (YARN-5220),
through distributed scheduling (YARN-2877), as well as the scheduling of containers based
on actual node utilization (YARN-1011) and the container promotion/demotion (YARN-5085).
