Daniel Templeton created YARN-5685: -------------------------------------- Summary: Non-embedded HA failover is broken Key: YARN-5685 URL: https://issues.apache.org/jira/browse/YARN-5685 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Affects Versions: 3.0.0-alpha1, 2.9.0 Reporter: Daniel Templeton Assignee: Daniel Templeton Priority: Critical
YARN-4559 broke RM HA when embedded automatic failover is disabled. The {{ZKRMStateStore}} will now only start its monitoring thread when automatic failover not enabled (which is patently useless). I presume the intended change was to have the monitoring thread started when automatic failover is not *embedded*. If HA is enabled with automatic failover enabled and embedded failover disabled, all RMs all come up in standby state. To make one of them active, the {{--forcemanual}} flag must be used when manually triggering the state change. Should the active go down, the standby will not become active and must be manually transitioned with the {{--forcemanual}} flag. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
