I don't think I have stored any very large objects. Could a bug in my

Which CDH3? u1,2, or 3?
So, I guess that's OK.
However, I wasn't hitting it that hard. I had 4 clients each writing about
1000 bytes about 2/second.
Thats not hard.
What is a Fat Cell, and how do I query the number of Regions/Server?
Fat cells is a fuzzy term for entries that are megabytes in size...>
10MB or so.
To find out how many regions, you look at the regionserver UI.
