Wilfred Spiegelenburg commented on MAPREDUCE-7278: -------------------------------------------------- [~tarunparimi] I have added you to the contributor list for the project and assigned the jira to you. The test you describe I think can be converted into a test using a {{MiniMRYarnCluster}} like what is done in the TestSpeculativeExecution. Did you look at that possibility? > 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, 3.4.0 > Reporter: Tarun Parimi > Assignee: Tarun Parimi > Priority: Major > Attachments: MAPREDUCE-7278.001.patch, MAPREDUCE-7278.002.patch, > 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.
