Subject [jira] [Updated] (YARN-6828) [Umbrella] Container preemption using OPPORTUNISTIC containers
Date Sat, 15 Jul 2017 16:51:01 GMT

     [ 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.
