ncl_MapReduceSim(MRSim)

MapReduce Simulator for Scheduling and Provisioning Algorithms.

Summary

  • MRSim runs a MapReduce procedures with the specific number of mappers/reducers and a specific scheduling/provisioning algorithm.
  • Those parameters (number of mappers/reducers, sizes of input data, InputSplits,scheduling algorithm, and provisioning algorithm) can be set the configuration file. Thus, you can test a MapReduce processes in various kinds of situations.

How to run

  • The configuration file is mr.properties, that defines the whole system and application parameters.
  • Build: use ant and run ant build.
  • Run: Run MRRun.bat for Windows, or ./MRRun.sh for Linux.
  • The result of written to mr/mrlog.csv. The log format is as follows:
