Method Detail

map

public void map(Chunk c)

Description copied from class: MRTask2

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 MRTask2<OrderTsk>

reduce

public void reduce(OrderTsk ot)

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<OrderTsk>

postGlobal

public void postGlobal()

Overrides:

postGlobal in class MRTask2<OrderTsk>
