It contains all classes and plugins needed to run a Nutch job on a Hadoop cluster. Hadoop cluster doesn't have to be used for Nutch, indeed there are many other interesting applications for it - so the core Hadoop is independent of any Nutch classes. So, as the job is submitted to the cluster, there must be a way to transmit all necessary implementation classes so that tasks on individual nodes could execute the Nutch code. This is the purpose of the job file - it is then expanded on each node, and all classes and plugins are loaded by a task's classloader. -- Best regards, Andrzej Bialecki <>< ___. ___ ___ ___ _ _ __________________________________ [__ || __|__/|__||\/| Information Retrieval, Semantic Web ___|||__|| \| || | Embedded Unix, System Integration http://www.sigram.com Contact: info at sigram dot com ------------------------------------------------------------------------- Using Tomcat but need to do more?
