Description:

Lua-MapReduce framework implemented in Lua using luamongo driver and MongoDB as storage. It follows Iterative MapReduce for training of Machine Learning statistical models. Documentation stills almost inexistent, but two examples are provided:

• WordCount task (MapReduce example)
• APRIL-ANN toolkit digits classification task (Iterative MapReduce example)

Changes to previous version:

• Updated to work with luamongo v0.5.0, which uses C++ driver legacy-1.1.0
