Renan DelValle created AURORA-1944: -------------------------------------- Summary: Aurora is unable to elect leader after losing ZK for an extended period of time Key: AURORA-1944 URL: https://issues.apache.org/jira/browse/AURORA-1944 Project: Aurora Issue Type: Bug Components: Scheduler Environment: Running on 0.17.0 Reporter: Renan DelValle
Using Apache Curator as the Zookeeper library causes an issue where Aurora is unable to elect a leader if Zookeeper loses quorum for an extended period of time. Scheduler seems to crash around: {{W0802 14:01:14.436 [TaskEventBatchWorker, SchedulerLifecycle] Failed to leave leadership: org.apache.aurora.common.zookeeper.SingletonService$LeaveException: Failed to abdicate leadership of group at /aurora/scheduler }} When the init system brings the scheduler back up, it is unable to elect a leader if ZK is still down. Once the scheduler enters this state, it is unable to snap out of it until it is manually restarted. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
