Hi,
Compiling Nutch 1.3 with patch NUTCH-993 (newest patch) and configuring
"mapreduce.job.jar.unpack.pattern" and "plugin.folders" according to
issue NUTCH-937 still won't allow me to run the stand-alone job jar.
What else should I patch/configure in order to do so? The command I use
is "hadoop jar nutch-1.3.job org.apache.nutch.crawl.Crawl /urls -dir
/root". This results in the stacktrace below. (I guess a plugin folder
is referenced that does not exist.)
