Abstract
A computer manages a cache for a MapReduce application based on a distributed file system that includes one or more storage medium by receiving a map request and receiving parameters for processing the map request. The parameters include a total data size to be processed, a size of each data record, and a number of map requests executing simultaneously. The computer determines a cache size for processing the map request, wherein the cache size is determined based on the received parameters for processing the map request and a machine learning model for a map request cache size and reads, based on the determined cache size, data from the one or more storage medium of the distributed file system into the cache. The computer processes the map request and writes an intermediate result data of the map request processing into the cache, based on the determined cache size.
