<P>PROBLEM TO BE SOLVED: To make a processing with overlapping sections reduced possible when only a parameter is subjected to processing of a plurality of different patterns in Map Reduce processing. <P>SOLUTION: When a job is given to Mapper or Reducer, the Mapper or Reducer detects parameter information including a parameter value, a use position, and a usage source function of the job, and stores them in a distributed file system. When a new job is given to the Mapper or the Reducer, the Mapper or Reducer detects new parameter information including a parameter value, a use position, and a usage source function of the job, compares the new parameter information with the parameter information stored in the distributed file system, integrates jobs of overlapping sections independent of the parameter, and makes the Mapper or Reducer execute while sharing the overlapping sections of the integrated jobs. <P>COPYRIGHT: (C)2012,JPO&INPIT |
