Abstract
A system and a method for spill management during the shuffle phase of a map-reduce job performed in a distributed computer system on distributed files. A spilling protocol is provided for handling the spilling of intermediate data based on at least one popularity attribute of key-value pairs of the input data on which the map-reduce job is performed. The spilling protocol includes an assignment order to storage resources belonging to the computer system based on the at least one popularity attribute. The protocol can be deployed in computer systems with heterogeneous storage resources. Additionally, pointers or tags can be assigned to improve shuffle phase performance. The distributed file systems that are most suitable are ones usable by Hadoop, e.g., Hadoop Distributed File System (HDFS).
