Method Detail

setupLocal

public void setupLocal()

Description copied from class: MRTask

Override to do any remote initialization on the 1st remote instance of this object, for initializing node-local shared data structures.

Overrides:

setupLocal in class MRTask<FrameUtils.Vec2ArryTsk>

map

public void map(Chunk c)

Description copied from class: MRTask

Override with your map implementation. This overload is given a single local input Chunk. It is meant for map/reduce jobs that use a single column in a input Frame. All map variants are called, but only one is expected to be overridden.

Overrides:

map in class MRTask<FrameUtils.Vec2ArryTsk>

reduce

public void reduce(FrameUtils.Vec2ArryTsk other)

Description copied from class: MRTask

Override to combine results from 'mrt' into 'this' MRTask. 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 MRTask<FrameUtils.Vec2ArryTsk>
