Subject Re: distributing a time consuming single reduce task

Thanks very much Steve!

The clustering part of the code is really a blackbox and there isn't much
to do as far as restructuring. I ended up breaking the big input file into
smaller ones and I am letting it running on the cluster. I will know in the
morning if it successfully or not. But, I will consider using Mahout for
clustering since it is built-in with the mapreduce. I will let you know how
that goes if you are interested.

Thanks very much once again for your kind responses!
