Arun Suresh commented on YARN-6828: ----------------------------------- Opening this as an umbrella JIRA as per [~leftnoteasy]'s request. Also created branch YARN-6828. > [Umbrella] Container preemption using OPPORTUNISTIC containers > -------------------------------------------------------------- > > Key: YARN-6828 > URL: https://issues.apache.org/jira/browse/YARN-6828 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Arun Suresh > Assignee: Arun Suresh > > This is based on discussions with [~kasha] and [~kkaranasos]. > 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. -- 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
