I am trying to get nutch/hadoop to run on 3 servers with SUSE linux.
I have followed the Nutch Hadoop Tutorial and everything works find (I
can run bin/hadoop dfs –ls), but when I run “bin/nutch inject crawldb
urls” I get this error.

I have set the JAVA_HOME variable in hadoop-env.sh to
/usr/java/jdk1.5.0_07/ but nutch still tells me that I use version 48.0
(java 1.4).
I have also tried to set the JAVA_HOME variable in bin/nutch but with
the same result.
