Method Detail

reduce

public void reduce(ProfileCollectorTask that)

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<ProfileCollectorTask>

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<ProfileCollectorTask>

priority

public byte priority()

Overrides:

priority in class MRTask<ProfileCollectorTask>
