public RebalanceTask(H2O.H2OCountedCompleter cmp,
                     Vec... srcVecs)

Method Detail

logVerbose

public boolean logVerbose()

Description copied from class: DTask

Override to remove 2 lines of logging per RPC. 0.5M RPC's will lead to 1M lines of logging at about 50 bytes/line produces 50M of log file, which will swamp all other logging output.

Overrides:

logVerbose in class DTask<RebalanceDataSet.RebalanceTask>

map

public void map(Chunk[] chks)

Description copied from class: MRTask

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 MRTask<RebalanceDataSet.RebalanceTask>
