      extended by org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.plans.DotMRPrinter.InnerPlan
All Implemented Interfaces:
Serializable, Cloneable, Iterable<DotMRPrinter.InnerOperator>
Enclosing class:
DotMRPrinter

public static class DotMRPrinter.InnerPlan
extends OperatorPlan<DotMRPrinter.InnerOperator>

Helper class to represent the relationship of map, reduce and combine phases in an MR operator. Each MR operator will have an inner plan of map -> (combine)? -> (reduce)? inner operators. The inner operators contain the physical plan of the execution phase.
