nutch-09 start problem
Hi,
I tried to setup nutch 0.9, but when I execute my script I get following error.
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/hadoop/util/PlatformName (Unsupported major.minor version 49.0)

Nutch 0.9 is an official release. Very young, but official, nonetheless.
t.n.a.

Hi Ratnesh,
I'm not sure that declaring Nutch 0.9 an "unstable" version is an entirely
appropriate label -- it's been through several stress tests by the
committers so far, and it seems to be performing well enough -- so much so
that we decided it was worthwhile to make a release of it :). I believe that
the user's problem below had to do with not running Nutch using JDK 5 (now,
a requirement).
Cheers,
Chris

I thnk that nutch-0.9 is unstable version , and it's not for developement
purpose but I am not sure enough.
we have used nutch-0.8.1. and it's working fine without an error .
and What I feel that you will get enough support from the list if you have
nutch-0.8 since most of us have used with this version.
But' it's encouraging working with new version , so I will appreciate if you
update your work on the list if you come up with any solution so that others
can take a help from this.
Thnx

Hi there,
Nutch 0.9 requires JDK 5 to run. What version of Java are you using? You
need to upgrade to 1.5.xx in order to run.
HTH,
Chris
