Method Detail

map

public void map(Chunk xs,
                Chunk ys)

Description copied from class: MRTask2

Override with your map implementation. This overload is given two local Chunks. All map variants are called, but only one is expected to be overridden.

Overrides:

map in class MRTask2<LR2.CalcSumsTask>

reduce

public void reduce(LR2.CalcSumsTask lr1)

Description copied from class: MRTask2

Override to combine results from 'mrt' into 'this' MRTask2. Both 'this' and 'mrt' are guaranteed to either have map() run on them, or be the results of a prior reduce(). Reduce is optional if, e.g., the result is some output vector.

Overrides:

reduce in class MRTask2<LR2.CalcSumsTask>
