POValueInputTez

public POValueInputTez(OperatorKey k)

Method Detail

getTezInputs

public java.lang.String[] getTezInputs()

Specified by:

getTezInputs in interface TezInput

replaceInput

public void replaceInput(java.lang.String oldInputKey,
                         java.lang.String newInputKey)

Specified by:

replaceInput in interface TezInput

addInputsToSkip

public void addInputsToSkip(java.util.Set<java.lang.String> inputsToSkip)

Description copied from interface: TezInput

Add to the list of inputs to skip download if already available in vertex cache

Specified by:

addInputsToSkip in interface TezInput

attachInputs

public void attachInputs(java.util.Map<java.lang.String,org.apache.tez.runtime.api.LogicalInput> inputs,
                         org.apache.hadoop.conf.Configuration conf)
                  throws ExecException

Description copied from interface: TezInput

Attach the inputs to the operator. Also ensure reader.next() is called to force fetch the input so that all inputs are fetched and memory released before memory is allocated for outputs

Specified by:

attachInputs in interface TezInput

Parameters:

inputs - available inputs

conf - configuration

Throws:

ExecException

getNextTuple

public Result getNextTuple()
                    throws ExecException

Overrides:

getNextTuple in class PhysicalOperator

Throws:

ExecException

setInputKey

public void setInputKey(java.lang.String inputKey)

illustratorMarkup

public Tuple illustratorMarkup(java.lang.Object in,
                               java.lang.Object out,
                               int eqClassIndex)

Description copied from interface: Illustrable

input tuple mark up to be illustrate-able

Specified by:

illustratorMarkup in interface Illustrable

Parameters:

in - input tuple

out - output tuple before wrapped in ExampleTuple

eqClassIndex - index into equivalence classes in illustrator

Returns:

tuple

visit

public void visit(PhyPlanVisitor v)
           throws VisitorException

Description copied from class: Operator

Specified by:

visit in class PhysicalOperator

Parameters:

v - Visitor to visit with.

Throws:

VisitorException - if the visitor has a problem.

supportsMultipleInputs

public boolean supportsMultipleInputs()

Description copied from class: Operator

Indicates whether this operator supports multiple inputs.

Specified by:

supportsMultipleInputs in class Operator<PhyPlanVisitor>

Returns:

true if it does, otherwise false.

supportsMultipleOutputs

public boolean supportsMultipleOutputs()

Description copied from class: Operator

Indicates whether this operator supports multiple outputs.

Specified by:

supportsMultipleOutputs in class Operator<PhyPlanVisitor>

Returns:

true if it does, otherwise false.

name
