Nutch Trunk Java requirement
On the current nutch trunk, what is the minimum Java implementation that is required to run it? I am currently on Sun Java 5.0 (binary JRE) and am getting errors of the following nature. bin/nutch crawl urls -dir crawl -depth 3 -topN 50 Exception in thread main java.lang.UnsupportedClassVersionError: Bad version number in .class file etc. Any help much appreciated! Chris.

Hi: I have got the same error. And I installed jdk 1.6, then it works. It seems a bit weird because I see the javac requirement in the build.xml is 1.5 but it broke. I guess maybe hadoop jar was compiled in java 1.6 and class compatibility is 1.6 so you can't run it in java 1.5. yanky 2009/3/25 Chris Muktar ch...@wikijob.co.uk On the current nutch trunk, what is the minimum Java implementation that is required to run it?

Yepp. Hands up - also the same - but only with the newest version (0.9) the old version 0.8 seams to work yanky young wrote: Hi: I have got the same error. And I installed jdk 1.6, then it works.

Re: Nutch Trunk Java requirement
Nutch trunk requires java 6 because the current Hadoop version we are using requires java 5. We need to change the java requirement in the build.xml.

Sorry, current hadoop version requires java 6 not java 5. Dennis Kubes wrote: Nutch trunk requires java 6 because the current Hadoop version we are using requires java 5.
