I am executing a MapReduce task. I have specified the mapred.map.tasks property to 20 & mapred.reduce.tasks to 0. But still I am getting a different number of mapper & reducer tasks. My command is
hadoop jar Example.jar Example abc.txt Result \ -D mapred.map.tasks = 20 \ -D mapred.reduce.tasks =0
Can anyone help me in understanding what is the problem here & how can I fix this?
