You can check the Cloudera Training Videos, where is a screencast explaining how to develop
Hadoop using Eclipse.

Now, For working with Hadoop APIs using Eclipse, for developing applications based on Hadoop,
you can use the Kamasphere Plugin for Hadoop Development, or if you are a NetBeans user, they
have a module for that.

Thanks Marco ! 
I was trying to use CDH3 with eclipse and not able to know why eclipse complains for the import
statement for hadoop apis when cloudera already includes them. 

I did not understand how CDH3 works with eclipse, does it download hadoop apis when we add
svn urls ?

Can you see all tutorial that Cloudera has on its site 

Can you check the CDH3 Official Documentation and the last news about 
the new release:

No, CDH beta 3 has with all required tools to work with Hadoop, even 
more applications like HUE, Oozie, Zookepper, Pig, Hive, Chukwa, HBase, 
Flume, etc

The Cloudera' colleagues has a excelent work packaging the most used 
applications with Hadoop on a single virtual machine for testing and 
they did a better approach to use Hadoop. 

They has Red Hat and Ubuntu/Debian compatible packages to do more easy 
the installation, configuration and use of Hadoop on these operating 

Please, read http://docs.cloudera.com

Do you set JAVA_HOME, and HADOOP_HOME on your system? 

If you have any doubt with this, you can check the excellent DZone' 
refcards about "Getting Started with Hadood" and "Deploying Hadoop" 
written by Eugene Ciurana( http://eugeneciurana.eu ), VP of Technology at
