hi Cosmin,
>I'll do my best. My expertise in in HBase and I'll have to figure out Jackrabbit first. So don't take this as a commitment :)
>I couldn't find the sandbox in any of the git repos. Is it only in SVN?
you could find the sandbox source code under http://svn.apache.org/repos/asf/jackrabbit/sandbox/jackrabbit-hadoop
>So first I'll make the current code run so I could better understand it, then I'll start working on the new one. I don't think it's a huge amount of work, but I'm doing this in my spare time so it could take >a while :)
Every input is welcome and don't stress yourself :-)
greets
claus
