RE: Hadoop JARs and Eclipse
If I am running from built code that was installed with
mvn install
Do I need to change the pom.xml file to reflect that I am using local repository?
Thanks,
John

If your goal is to simply build an application, then you can use a Maven project. Why do you require the whole of Hadoop's projects itself on Eclipse when you can simply have the dependencies via a maven pom.xml?

The following is what you can use in a simple maven app, to include all necessary dependencies automatically, for example:

<dependencies>
    <dependency>
      <groupId>org.apache.hadoop</groupId>
      <artifactId>hadoop-client</artifactId>
      <version>2.0.4-alpha</version>
    </dependency>
  </dependencies>

Then importing this project into Eclipse (using m2e plugin) would be equivalent to "Adding all relevant Hadoop JARs to Eclipse".
