Hi Sujan, did you also place the hadoop.dll on a place where it is found? Sorry, but I have no experience what the correct place would be (I'm only on Linux and even no Windows available for testing). Please, check, e.g. [1].
Ev. runtime/local/lib/native/name_of_your_platform/, see lib/native/README.txt and also how the platform name is determined in bin/nutch I hope you'll find a solution. Would you mind to add your findings to [2]? We would really appreciate if someone could update this page - it's horribly outdated! If yes, just ask for write access to the Nutch wiki on this list. Thanks, Sebastian [1] http://stackoverflow.com/questions/30964216/hadoop-on-windows-yarn-fails-to-start-with-java-lang-unsatisfiedlinkerror [2] https://wiki.apache.org/nutch/GettingNutchRunningWithWindows On 08/08/2016 12:01 PM, Sujan Suppala wrote: > Hi Sebastian, > > I am launching Nutch in local mode.
