[ https://issues.apache.org/jira/browse/MAPREDUCE-220?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Arun C Murthy updated MAPREDUCE-220: ------------------------------------ Status: Open (was: Patch Available) TaskStatus isn't really a 'public' api (MAPREDUCE-1623 & HADOOP-5073). Thus TaskStatus.ResourceStatus shouldn't be exposed directly to the end-user. We probably should convert the fields in ResourceStatus into Counters and use that as the primary interface for the end-user, also we should store them into JobHistory etc. > Collecting cpu and memory usage for MapReduce tasks > --------------------------------------------------- > > Key: MAPREDUCE-220 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-220 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Components: task, tasktracker > Reporter: Hong Tang > Assignee: Scott Chen > Fix For: 0.22.0 > > Attachments: MAPREDUCE-220-v1.txt, MAPREDUCE-220.txt > > > It would be nice for TaskTracker to collect cpu and memory usage for > individual Map or Reduce tasks over time. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
