CoHadoop: Flexible Data Placement and Its Exploitation in Hadoop

Summary: CoHadoop extends Hadoop with application-supplied related-file hints, enabling fault-tolerant physical colocation without imposing a data format. It exploits colocated partitions for efficient map-only joins and sessionization, outperforming repartitioning and partition-aware baselines. (summarized by gpt-5.6-luna on Jul 24 2026)
