Amar Kamat resolved MAPREDUCE-2105. ----------------------------------- Tags: gridmix emulation plugin Resolution: Fixed Fix Version/s: 0.23.0 Assignee: Amar Kamat Committed as part of MAPREDUCE-2106. > Simulate Load Incrementally and Adaptively in GridMix3 > ------------------------------------------------------ > > Key: MAPREDUCE-2105 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-2105 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: contrib/gridmix > Affects Versions: 0.22.0 > Reporter: Ranjit Mathew > Assignee: Amar Kamat > Fix For: 0.23.0 > > > Tasks launched by GridMix3 should incrementally and adaptively simulate load > (I/O, CPU, memory, etc.) rather than doing > everything upfront and then sleeping. This helps in evening out the load when > fine-grained information from the original > Task is not available and greater accuracy when it is. > By "incremental" I mean having several iterations corresponding to > appropriate phases/time-slices. By "adaptive" I mean > taking the existing load into account before inflicting additional load to > meet a target load (we are unlikely to achieve > 100% fidelity as we overshoot or undershoot with each iteration). -- This message is automatically generated by JIRA.
