getNextTuple

public Result getNextTuple()
                    throws ExecException

Description copied from class: POLocalRearrange

Calls getNext on the generate operator inside the nested physical plan. Converts the generated tuple into the proper format, i.e, (key,indexedTuple(value))

Overrides:

getNextTuple in class POLocalRearrange

Throws:

ExecException

clone

public POLocalRearrangeTez clone()
                          throws java.lang.CloneNotSupportedException

Make a deep copy of this operator.

Overrides:

clone in class POLocalRearrange

Throws:

java.lang.CloneNotSupportedException

See Also:

Do not use the clone method directly. Operators are cloned when logical plans are cloned using {@link LogicalPlanCloner}

name

public java.lang.String name()

Overrides:

name in class POLocalRearrange
