[jira] [Commented] (AURORA-96) Implement fair share scheduling for non-production tasks

["Stephan Erb (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AURORA-96?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14259072#comment-14259072 ] 

Stephan Erb commented on AURORA-96:
-----------------------------------

We would be interested in this one. When two jobs have running and pending instances each, we would like the pending instances to be started according to dominant resource fairness (e.g., if one job requires two times more resources than another, it only gets halve the number of instances).

Is it correct that currently the scheduling order is only given implicitly by the group backoff timers computed in TaskGroups.java?

> Non-production tasks are allocated on a first-come first-served basis.  This means that anybody could hold the entire cluster hostage (intentionally or otherwise).  The scheduler should correct this by ensuring that non-production resources are distributed fairly.
