Method Detail

map

public void map(Chunk[] cs)

Description copied from class: MRTask2

Override with your map implementation. This overload is given an array of local input Chunks, for Frames with arbitrary column numbers. All map variants are called, but only one is expected to be overridden.

Overrides:

map in class MRTask2<Summary2.PrePass>

reduce

public void reduce(Summary2.PrePass other)

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<Summary2.PrePass>

finishUp

public Summary2.PrePass finishUp()
