Summary: MapReduce tasks timing out when spends more time on MultipleOutputs#close Key: MAPREDUCE-7369 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7369 Project: Hadoop Map/Reduce Issue Type: Bug Affects Versions: 3.3.1 Reporter: Prabhu Joseph Assignee: Prabhu Joseph MapReduce tasks timing out when spends more time on MultipleOutputs#close. MultipleOutputs#closes takes more time when there are multiple files to be closed & there is a high latency in closing a stream. {code} 2021-11-01 02:45:08,312 INFO [AsyncDispatcher event handler] org.apache.hadoop.mapreduce.v2.app.job.impl.TaskAttemptImpl: Diagnostics report from attempt_1634949471086_61268_m_001115_0: AttemptID:attempt_1634949471086_61268_m_001115_0 Timed out after 300 secs {code} MapReduce task timeout can be increased but it is tough to set the right timeout value. The timeout can be disabled with 0 but that might lead to hanging tasks not getting killed. The tasks are sending the ping every 3 seconds which are not honored by ApplicationMaster. It expects the status information which won't be send during MultipleOutputs#close. This jira is to add a config which considers the ping from task as part of Task Liveliness Check in the ApplicationMaster. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
