There are at least 2 more ways to get hadoop. Clement has an 
account and is working on hadoop there. So you could just checkout his
svn tree and get the latest port:

1) just fetch his redports.org repository compressed as tar.bz2:

fetch http://redports.org/~clement/svn.tar.bz2
tar xvf svn.tar.bz2

2) you need devel/subversion installed for that

svn co https://svn.redports.org/clement/

Now you need to manually add the hadoop lines in GIDs/UIDs to your
/usr/ports/GIDs|UIDs files as well as copying over the devel/hadoop
directory to /usr/ports.
