Ok. Now imagine that all plugins are packed together in a Jar file (as is the case with Nutch). Is your method still going to work? Nope. getPluginRootDir() may still return some non-null value (not sure about that), but the resources are not available as files because they are packed into a Jar. Now, you may have tested your method and found that it does indeed work - but the reason is a bit obscure: the bin/nutch and bin/hadoop scripts add your build/ directory to the classpath, so that you can locally test the latest versions of the code without creating the *.job file. However, when you run your code on a Hadoop cluster your local build/ directory is no longer accessible, and your method will mysteriously fail - or even worse, you may get a different version of a resource from an older version of the build/ directory found on Hadoop tasktracker nodes ... > > Andrzej's idea is limited(?) since i cannot get resources from conf dir. Absolutely not - that's how the whole Configuration system works. -- Best regards, Andrzej Bialecki <>< ___. ___ ___ ___ _ _ __________________________________ [__ || __|__/|__||\/| Information Retrieval, Semantic Web ___|||__|| \| || | Embedded Unix, System Integration http://www.sigram.com Contact: info at sigram dot com ------------------------------------------------------------------------- Take Surveys.
