Dynamic Resource Allocation for MapReduce with ... - Raouf Boutaba
MapReduce is a popular computing paradigm for large-scale data processing in cloud computing. However, the slot-based MapReduce system (e.g., Hadoop MRv1) can suffer from poor performance due to its unoptimized resource allocation. To address it, this paper identifies and optimizes the resource allocation from three key aspects. Dynamic Job Ordering and Slot Configurations for MapReduce ...
