Note that the following slides are from last term. When I have time I will be tweaking them. There's some Javascript that puts an "updated" note beside any files that change.

Part 2: MapReduce Algorithm Design

Topics

  • MapReduce programming model
  • Cloud computing and datacenters
  • Hadoop API
  • Hadoop physical execution
  • MapReduce design patterns
  • Intermediate aggregation and combiners
  • Partitioning, grouping, and sorting

Readings
