Hung Tasks never time out. --------------------------- Key: MAPREDUCE-4089 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4089 Project: Hadoop Map/Reduce Issue Type: Bug Components: mrv2 Affects Versions: 0.23.2, 2.0.0, trunk Reporter: Robert Joseph Evans Assignee: Robert Joseph Evans Priority: Blocker
The AM will timeout a task through mapreduce.task.timeout only when it does not hear from the task within the given timeframe. On 1.0 a task must be making progress, either by reading input from HDFS, writing output to HDFS, writing to a log, or calling a special method to inform it that it is still making progress. This is because on 0.23 a status update which happens every 3 seconds is counted as progress. -- This message is automatically generated by JIRA.
