The Research of The Scheduling Algorithm of MapReduce Model under The Hadoop
Liu We · Journal of Guangxi University for Nationalities · 2014
Aiming at the shortage of Hadoop default FIFO scheduling algorithm and Fair scheduling algorithm,we introduce an adaptive scheduler algorithm based on priority.system can assign appropriate computing resources and execution time to job based on its priority,at the same time,with the feedback message fromTaskTracker node system can dynamically adjust the length of active queue,in order to achieve the load balance and improve the efficiency of the system.
