Key: MAPREDUCE-3528 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3528 Project: Hadoop Map/Reduce Issue Type: Bug Components: mr-am, mrv2 Affects Versions: 0.23.0 Reporter: Siddharth Seth TaskHeartbeatHandler sleeps for 'mapreduce.task.timeout' - between each check. If a task/NM goes bad immediately after starting a task - the timeout is detected in ~2x the configured timeout interval. -- This message is automatically generated by JIRA.
