[syed kather <in...@gmail.com>]

Team,
    Is there a way to increase to Number of Reducer . In Map reduce Program
.

 I had increased in configuration mapred.tasktracker.reduce.tasks.maximum =
2 . Is there a way where we can increase in Program?



            Thanks and Regards,

Hi Syed,

Please do go through the tutorial completely, it helps you understand
whats possible and whats not, and how to do certain things:
http://hadoop.apache.org/common/docs/stable/mapred_tutorial.html#Reducer

As it mentions:
"The number of reduces for the job is set by the user via
JobConf.setNumReduceTasks(int)."
API: http://hadoop.apache.org/common/docs/stable/api/org/apache/hadoop/mapred/JobConf.html#setNumReduceTasks(int)
