Hello,
Could someone please help me to understand these configuration parameters in
depth.
mapred.map.tasks and mapred.reduce.tasks
It is mentioned that default value of these parameters is 2 and 1.
*What does it mean?*
Does it mean 2 maps and 1 reduce per node.
Does it mean 2 maps and 1 redu

If I am correct :
For setting mappers/node --- mapred.tasktracker.map.tasks.maximum
For setting reducers/node --- mapred.tasktracker.reduce.tasks.maximum
For setting mappers/job mapred.map.tasks (applicable for whole cluster)
For setting reducers/job mapred.reduce.tasks(same)
You can
