Subject Re: HRegionPartitioner breaks my configuration

Hi,
thank you for your input.

I've been doing it exactly that way. Jars appear in the classpath
without problems.
But I am unable to transfer hbase-site.xml to the mapper's classpath.

So now I will try adding hbase-site.xml to the CP hadoop-env.sh.

The addDependencyJars mechanism does not work for xml files :(
