cascading.flow.hadoop.planner.rule.partitioner.StreamedAccumulatedTapsHashJoinPipelinePartitioner

All Implemented Interfaces:

cascading.flow.planner.rule.Rule

public class StreamedAccumulatedTapsHashJoinPipelinePartitioner
extends cascading.flow.planner.rule.partitioner.ExpressionRulePartitioner

This rule accounts for a Tap marked as both streamed and accumulated, but is streamed in one pipeline and accumulated in another pipeline.

The rule leverages the ability to not capture some matched edges, that represent paths that should not be included in the result pipeline.
