I am using TableMapReduceUtil.initTableMapperJob to initiate a map reduce job that scans the entire table and processes records in it.
I wanted to know if I can control/hint to the framework for setting the number
of mappers.
I was searching online and I see that JobConf's conf.setNumMapTasks(int num) is
deprecated. I tried setting the number of tasks in the code
c.set("mapred.map.tasks", "5"); or
c.setInt("mapred.map.tasks", 5);
but that doesn't work.
thanks
