Each usable event will create 1K > events over all events could be 5k*1k events for 5K cluster > # Event processing is blocked till new events are added to queue. > Solution : > # Add another async Event handler similar to scheduler. > # Instead of adding events to dispatcher directly call RMApp event handler. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
