Summary: Speculative execution behavior is observed even when mapreduce.map.speculative and mapreduce.reduce.speculative are false Key: MAPREDUCE-7278 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7278 Project: Hadoop Map/Reduce Issue Type: Bug Components: task Affects Versions: 2.8.0 Reporter: Tarun Parimi Attachments: Screen Shot 2020-04-30 at 8.04.27 PM.png When a failed task attempt container is stuck in FAIL_FINISHING_CONTAINER state for some time, we observe two task attempts are launched simultaneously even when speculative execution is disabled. This results in the below message shown in the killed attempts, indicating speculation has occurred. This is an issue for jobs which require speculative execution to be strictly disabled. !Screen Shot 2020-04-30 at 8.04.27 PM.png! -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
