I kinda doubt it.
In my tests with pseudo-distributed mode the whole cdh hadoop is
running
with the same user (as it is the vanilla hadoop in the test), so i
should not have such problems of permissions.
How did you install CDH3? From the issue I referenced below, the user
said:
Problem solved, sort of. I gave up on using the CDH3 rpms and
went back to installing hadoop in /opt/hadoop and running it as user
hadoop (with the apache scripts) as I'm accustomed to. It's still
CDH3, just installed via tarball. In this configuration, my job runs
fine.

Sounds similar to this:

No resolution, but the reporting user's last guess was that it had
something to do with permissions issues on the directory where a job
jar's bundled jars (such as the Nutch plugins?) get deployed by the
JobTracker/TaskTracker.

Hello list,
as previously reported, I'm having some issues running nutch in
distributed mode on our cluster running cloudera's hadoop
distribution
0.20.2+737.
the mentioned problem is:
Caused by: java.lang.RuntimeException: x point
org.apache.nutch.net.URLNormalizer not found.
at
org.apache.nutch.net.URLNormalizers.<init>(URLNormalizers.java:122)
at
org.apache.nutch.crawl.Injector
$InjectMapper.configure(Injector.java:68)
... 22 more
To try tackle down the problem i've setup a pseudo-distributed
node with
clean vanilla 0.20.2 hadoop and the aforementioned 0.20.2+737 by
cloudera.
running nutch on this pseudo-distributed cluster was successfull
with
the vanilla hadoop 0.20.2 but created the aformentioned exception
on the
cdh3.
This means to me, as mentioned in my previous email, that there
are some
compatibility issues with latest cdh3. This means, for me,
"downgrading"
to vanilla hadoop the whole cluster, unless you have a better idea.
Does anybody have a suggestion about this issue?
TIA
