Scott Chen commented on MAPREDUCE-961: -------------------------------------- I have filed the task scheduling order issue in MAPREDUCE-1198. I am working on it. > ResourceAwareLoadManager to dynamically decide new tasks based on current > CPU/memory load on TaskTracker(s) > ----------------------------------------------------------------------------------------------------------- > > Key: MAPREDUCE-961 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-961 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Components: contrib/fair-share > Affects Versions: 0.22.0 > Reporter: dhruba borthakur > Assignee: Scott Chen > Fix For: 0.22.0 > > Attachments: HIVE-961.patch, MAPREDUCE-961-v2.patch, > MAPREDUCE-961-v3.patch > > > Design and develop a ResouceAwareLoadManager for the FairShare scheduler that > dynamically decides how many maps/reduces to run on a particular machine > based on the CPU/Memory/diskIO/network usage in that machine. The amount of > resources currently used on each task tracker is being fed into the > ResourceAwareLoadManager in real-time via an entity that is external to > Hadoop. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
