Abstract (in Japanese) (See Japanese page) 
(in English) MapReduce is one of a framework to process large-scale data efficiently. Describing only two methods, Map and Reduce, distributed program can be implemented easily. In Hadoop which is a open source implementation of MapReduce, JobTracker (master program in Hadoop) assigns Map Tasks and Reduce Tasks to TaskTracker (slave program which execute the tasks). In a environment such that multiple Hadoop systems are running on a same cluster, computational resources should be shared by every Hadoop. Available computational resources of each Hadoop uctuates dynamically by behavior of other Hadoops. Then, a scheduler which schedule tasks to TaskTrackers properly, are required; we call it JobTracker Initiative Task Scheduler. In this paper, as a preliminary research of JobTracker Initiative Task Scheduler, we propose a method which decide the number of execution of task in order to use computation resources efficiently and based on a load on each computer. And we have shown results of our evaluations.
