Cindy Li created MAPREDUCE-4710: ----------------------------------- Summary: Add peak memory usage counter for each task Key: MAPREDUCE-4710 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4710 Project: Hadoop Map/Reduce Issue Type: New Feature Components: task Affects Versions: 1.0.2 Reporter: Cindy Li Priority: Minor
Each task has counters PHYSICAL_MEMORY_BYTES and VIRTUAL_MEMORY_BYTES, which are snapshots of memory usage of that task. They are not sufficient for users to understand peak memory usage by that task, e.g. in order to diagnose task failures, tune job parameters or change application design. This new feature will add two more counters for each task: PHYSICAL_MEMORY_BYTES_MAX and VIRTUAL_MEMORY_BYTES_MAX. -- This message is automatically generated by JIRA.
