Constructor Detail

FakeOutput

public FakeOutput(OutputContext outputContext,
                  int numPhysicalOutputs)

Constructor an instance of the LogicalOutput. Classes extending this one to create a LogicalOutput, must provide the same constructor so that Tez can create an instance of the class at runtime.

Parameters:

outputContext - the OutputContext which provides the Output with context information within the running task.

numPhysicalOutputs - the number of physical outputs that the logical output will
