[jira] [Created] (MAPREDUCE-4710) Add peak memory usage counter for each task
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.

[jira] [Created] (MAPREDUCE-4711) Append time elapsed since job-start-time for finished tasks
Ravi Prakash created MAPREDUCE-4711: --- Summary: Append time elapsed since job-start-time for finished tasks Key: MAPREDUCE-4711 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4711 Project: Hadoop Map/Reduce Issue Type: Bug Components: jobhistoryserver Affects Versions: 0.23.3 Reporter: Ravi Prakash Assignee: Ravi Prakash In 0.20.x/1.x, the analyze job link gave this information bq. The last Map task task_sometask finished at (relative to the Job launch time): 5/10 20:23:10 (1hrs, 27mins, 54sec) The time it took for the last task to finish needs to be calculated mentally in 0.23. I believe we should print it next to the finish time. -- This message is automatically generated by JIRA.
