Chinna Rao Lalam commented on HIVE-2495:
----------------------------------------

I have verified with trunk code if set a value for "mapred.reduce.tasks" this 
property it will take effect and it will start that many reducers.

Can u add u r scenario with little more details.

What is the suggested value for setting number of reducers is
http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/mapred/JobConf.html#setNumReduceTasks(int).
                
> set mapred.reduce.tasks does not work
