Vinod K V commented on MAPREDUCE-1218: -------------------------------------- bq. I have found that there is a mistake in the previous patch. Previously I made MemoryCalculatorPlugin extends ResourceCalculatorPlugin and LinuxMemoryCalculatorPlugin extends LinuxResourceCalculatorPlugin. But LinuxResourceCalculatorPlugin does not extend MemoryCalculatorPlugin. Good catch! {{DummyMemoryCalculatorPlugin}} needs to be deprecated still?. Other than that, +1 for the patch. Once that is done, and after Hudson blesses it, can you ask someone to commit this? Thanks for being patient! > Collecting cpu and memory usage for TaskTrackers > ------------------------------------------------ > > Key: MAPREDUCE-1218 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1218 > Project: Hadoop Map/Reduce > Issue Type: Sub-task > Affects Versions: 0.22.0 > Environment: linux > Reporter: Scott Chen > Assignee: Scott Chen > Fix For: 0.22.0 > > Attachments: MAPREDUCE-1218-rename.sh, MAPREDUCE-1218-v2.patch, > MAPREDUCE-1218-v3.patch, MAPREDUCE-1218-v4.patch, MAPREDUCE-1218-v5.patch, > MAPREDUCE-1218-v6.patch, MAPREDUCE-1218.patch > > > The information can be used for resource aware scheduling. > Note that this is related to MAPREDUCE-220.
