Karthik Kambatla updated YARN-6246: ----------------------------------- Summary: Identifying starved apps does not need the scheduler writelock (was: Move app starvation identification out of the update thread) > Identifying starved apps does not need the scheduler writelock > -------------------------------------------------------------- > > Key: YARN-6246 > URL: https://issues.apache.org/jira/browse/YARN-6246 > Project: Hadoop YARN > Issue Type: Sub-task > Components: fairscheduler > Affects Versions: 2.9.0 > Reporter: Karthik Kambatla > Assignee: Karthik Kambatla > > Given the update thread holds the scheduler write-lock, we are probably > better of computing starvation and identification of starved apps in a > different thread. > I am averse to adding a thread that runs on a *configurable timeout*, but > maybe we could trigger this thread after every update run, or do this in the > update thread but outside of the write-lock. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
