Rohith Sharma K S updated YARN-8404: ------------------------------------ Summary: RM Event dispatcher is blocked if ATS1/1.5 server is not running. (was: RM Recovery is delayed much if ATS1/1.5 server is not running. ) > RM Event dispatcher is blocked if ATS1/1.5 server is not running. > ------------------------------------------------------------------ > > Key: YARN-8404 > URL: https://issues.apache.org/jira/browse/YARN-8404 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Rohith Sharma K S > Assignee: Rohith Sharma K S > Priority: Critical > > It is observed that if ATS1/1.5 daemon is not running, RM recovery is delayed > as long as timeline client get timed out for each applications. By default, > timed out will take around 5 mins. If completed applications are more then > amount of time RM will wait is *(number of completed applications in a > cluster * 5 minutes)* which is kind of hanged. > Primary reason for this behavior is YARN-3044 YARN-4129 which refactor > existing system metric publisher. This refactoring made appFinished event as > synchronous which was asynchronous earlier. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
