If write your code within a Maven project (which you can open from Eclipse) then you should the following in your pom.xml:
* Define Cloudera repository: ... <repository> <id>cdh.repo</id> <url> https://repository.cloudera.com/content/groups/cloudera-repos</url> <name>Cloudera Repositories</name> <snapshots> <enabled>false</enabled> </snapshots> </repository> ... * Add Hadoop dependency: ... <dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-core</artifactId> <version>0.20.2-cdh3B4</version> </dependency> ... You can browse the Cloudera Maven repositories (for avail JARs and versions) at: https://repository.cloudera.com/ You'll find Hadoop/Pig/Hive/Sqoop/Zookeeper/Hbase/Flume/Oozie JARs (with all the *cdh3B4 of them versions working with each other) Then your app should run with the Cloudera releases of Hadoop/...etc. Hope this helps. Thanks.
