Subject Hive configuration property
Date Wed, 26 Sep 2012 12:28:40 GMT

Hi all,

I have doubt regarding below properties, is it a good practice to override below properties
in hive.

If yes, what is the optimal values for the following properties?

  set hive.exec.reducers.bytes.per.reducer=<number>
In order to limit the maximum number of reducers:
  set hive.exec.reducers.max=<number>
In order to set a constant number of reducers:
  set mapred.reduce.tasks=<number>
