cost of fairness. Alternatively, we propose a technique called Slot PreScheduling that can improve the data locality but with no impact on fairness. Finally, by combining these techniques together, we form a step-by-step slot allocation system called DynamicMR that
A. dynamic slot allocation technique. Dynamic Hadoop Fair Scheduler(DHFS).B. JOB SCHEDULING FOR MULTI-USER MAPREDUCE CLUSTERS Job scheduling process. Job scheduling in Hadoop is performed by the job master,which manages a number of worker nodes in the cluster. Slot allocation and load balancing Abstract-DynamicMR technique is used to allocate slots dynamically and to optimize the resource utilization. This technique consist of three modules they are slot allocation, speculative performance balancing and slot prescheduling. These three techniques suffers some problem. Mapreduce workload for dynamic job ordering and...

Tuning the number of map and reduce tasks for a job is important and easy to overlook.LimitingTaskSlotUsage - Hadoop Wiki LimitingTaskSlotUsage Limiting Task Slot Usage Job is consuming all task slots Job has taken too many reduce slots that are still waiting for maps to finish Job is referencing an external, limited resource (such as a ...
ordered in the queue is based on the Earliest Deadline First(EDF).Third, a Dynamic slot allocation technique is used that allocates and deal locates the map and reduce slots based on the deadline. Fourth, the slow running tasks that are identified as straggled tasks are run on the fast working nodes. An Efficient Dynamic Slot Allocation Based On Fairness ...

MapReduce has become an important paradigm for ... become the fundamental technique for cloud computing. DynamicMR: A Dynamic Slot Allocation Optimization ... 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.
DynamicMR: A Dynamic Slot Allocation Optimization… Because map slots might be fully utilized while reduce slots are empty, and vice-versa. We propose an alternative technique called Dynamic Hadoop Slot Allocation by keeping the slot-based model. It relaxes the slot allocation constraint to allow slots to be reallocated to either map or reduce tasks... DynamicMR: A Dynamic Slot Allocation Optimization…
