This should really second nature as Nutch heavily relies upon the underlying Hadoop infrastructure. Therefore you can check out (svn) the Hadoop sources into your Eclipse IDE and combine to debug this way. You can: - * Checkout the Hadoop version that should be used within Nutch 1.3 + * Checkout the Hadoop version that should be used within Nutch trunk * configure a Hadoop project similar to the Nutch project within your Eclipse IDE * add the Hadoop project as a dependent project of Nutch project * you can now also set break points within Hadoop classes like inputformat implementations etc.
