Subject [Lucene-hadoop Wiki] Update of "WordCount" by OwenOMalley
Date Wed, 28 Jun 2006 21:28:12 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Lucene-hadoop Wiki" for change notification.

The following page has been changed by OwenOMalley:
http://wiki.apache.org/lucene-hadoop/WordCount

------------------------------------------------------------------------------
  As an optimization, the reducer is also used as a combiner on the map outputs. This reduces
the amount of data sent across the network by combining each word into a single record.
  
  To run the example, the command syntax is[[BR]]
- bin/hadoop jar build/hadoop-*-examples.jar wordcount [-m <#maps>] [-r <#reducers>]
<in-dir> <out-dir>
+ bin/hadoop jar hadoop-*-examples.jar wordcount [-m <#maps>] [-r <#reducers>]
<in-dir> <out-dir>
