Hi, I am currently using hadoop 0.19.2 to run large data processing. But I noticed when the job is launched, there are only two map/reduce tasks running in the very beginning. after one heartbeat (5sec), another two map/reduce task is started. I want to ask how I can increase the map/reduce slots?
In the configuration file, I have already set "mapred.tasktracker.map(reduce).tasks.maximum" to 10, and "mapred.map(reduce).tasks" to 10. But there are still only 2 are launched. Eager to hear from your solutions! Best regards, Starry /* Tomorrow is another day. So is today. */
