[jira] [Updated] (YARN-6828) [Umbrella] Container preemption using
OPPORTUNISTIC containers
[ https://issues.apache.org/jira/browse/YARN-6828?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Arun Suresh updated YARN-6828:
------------------------------
Description:
Currently, the YARN schedulers selects containers for preemption only in response to a starved queue / app's request. We propose to allow the Schedulers to mark containers that are allocated over queue capacity/fair-share as Opportunistic containers.
This JIRA proposes to allow Schedulers to:
# Allocate all containers over the configured queue capacity/weight as OPPORTUNISTIC.
# Auto-promote running OPPORTUNISTIC containers of apps as and when their GUARANTEED containers complete.
