Changed TaskCounter.properties to provide textual description to the newly added counter. Thanks Owen for pointing it out. test-patch passed on my box. Changes to TaskCounter.properties should not affect the test cases. > Task counters should also report the total heap usage of the task > ----------------------------------------------------------------- > > Key: MAPREDUCE-2469 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-2469 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: task > Affects Versions: 0.23.0 > Reporter: Amar Kamat > Assignee: Amar Kamat > Labels: mapreduce > Attachments: 2469.v0.1.patch, mapreduce-2469-v1.1.patch, mapreduce-2469-v1.2.patch > > > Currently, the task counters report VSS and RSS usage of the task. The task counter should also report the total heap usage of the task also. The task might be configured with a max heap size of M but the task's total heap usage might only be H, where H < M. In such a case, knowing only M doesn't provide a complete picture of the task's memory usage. -- This message is automatically generated by JIRA.
