More experimenting:
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-core</artifactId>
<version>0.20.203.0</version>
<type>POM</type>
</dependency>
Works, but (as you indicate) gives the old Hadoop API.
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-mapred</artifactId>
<version>...</version>
<type>POM</type>
</dependency>
Doesn't work. I can't find a hadoop-mapred artifact when I search for one on
Maven Central <http://search.maven.org/>.
