Abstract
Embodiments of the present invention provide methods, systems, and computer program products for transferring data in a MapReduce framework. In one embodiment, MapReduce jobs are performed such that data spills are stored by mapper systems in memory and are transferred to reducer systems via one-sided RDMA transfers, which can reduce CPU overhead of mapper systems and the latency of data transfer to reducer systems.
