If you still want to try it, the source is in trunk/contrib/hadoop. To build it, you need the jar from the hadoop release 0.20.1 and the XtreemFS trunk (or release 1.2). Make sure to modify the path to the hadoop.jar in nbproject/project.properties. In order to use XtreemFS with hadoop, you need to load three jar files: the HadoopClient.jar, the XtreemFS.jar and the yidl.jar. You also have to add XtreemFS to your hadoop config:
<property> <name>fs.xtreemfs.impl</name> <value>org.xtreemfs.common.clients.hadoop.XtreemFSFileSystem</value> <description>The FileSystem for xtreemfs: uris.</description> </property>
The URLs for XtreemFS follow this scheme: xtreemfs://volumeName@dirServiceHost:32638/path
The userID and groupID can be set in the config options xtreemfs.client.userid and xtreemfs.client.groupid
