Constructor Detail

FakeInput

public FakeInput(InputContext inputContext,
                 int numPhysicalInputs)

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

Parameters:

inputContext - the InputContext which provides the Input with context information within the running task.

numPhysicalInputs - the number of physical inputs that the logical input will
