Hi, 
i am trying to run hive with limitation of mappers and reducers. 
i am trying to run : 

    set mapred.tasktracker.reduce.tasks.maximum = 10;
    set mapred.tasktracker.map.tasks.maximum = 10;
    or:
    set mapred.job.reduce=10;
    set mapred.job.maps=10;
    or:
    set mapred.map.tasks = 10;
    set mapred.reduce.tasks= 10;

none of those work, and i am getting 135 mappers... 
how can i limit it?

Thanks.
