Subject [jira] [Commented] (HIVE-2495) set mapred.reduce.tasks does not work
Date Tue, 15 Nov 2011 13:41:52 GMT


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

> Setting mapred.reduce.tasks does not work. In my opinion, we should provider a property
(eg. mapred.reduce.tasks.force) to make "mapred.reduce.tasks" working. Thus there is a way
to set a constant reduce for experienced people.
