Subject [Hadoop Wiki] Update of "FAQ" by QwertyManiac
Date Tue, 01 Mar 2011 16:58:21 GMT
Dear Wiki user,

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

The "FAQ" page has been changed by QwertyManiac.
The comment on this change is: Add some of Steve Loughran's thoughts on loading the cluster's
configuration in applications..


  Setting configuration properties as final is a common thing Administrators do, as is noted
in the [[http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/conf/Configuration.html|Configuration]]
API docs.
+ A better alternative would be to have a service serve up the Cluster's configuration to
you upon request, in code. [[HADOOP-5670|https://issues.apache.org/jira/browse/HADOOP-5670]]
may be of some interest in this regard, perhaps.
  == Can I write create/write-to hdfs files directly from map/reduce tasks? ==
  Yes. (Clearly, you want this since you need to create/write-to files other than the output-file
written out by [[http://hadoop.apache.org/core/docs/current/api/org/apache/hadoop/mapred/OutputCollector.html|OutputCollector]].)
