Jason Lowe created MAPREDUCE-7053: ------------------------------------- Summary: Timed out tasks can fail to produce thread dump Key: MAPREDUCE-7053 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7053 Project: Hadoop Map/Reduce Issue Type: Bug Affects Versions: 3.1.0, 3.0.1, 2.10.0, 2.9.1, 2.8.4, 2.7.6 Reporter: Jason Lowe
TestMRJobs#testThreadDumpOnTaskTimeout has been failing sporadically recently. When the AM times out a task it immediately removes it from the list of known tasks and then connects to the NM to request a thread dump followed by a kill. If the task heartbeats in after the task has been removed from the list of known tasks but before the thread dump signal arrives then the task can exit with a "org.apache.hadoop.mapred.Task: Parent died." message and no thread dump. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
