Subject Re: How set number of map and reduce can run simultaneously
Date Mon, 23 May 2011 16:58:35 GMT
I think I've to rephrase the question.

I set the "mapred.tasktracker.map.tasks.maximum" to 8, hoping that it
will run 8*10 map tasks in the whole cluster. But, it only run 8 tasks
simultaneously. Why this is happens?
