Subject Re: the files of one table is so big?

(Trying to answer with the very little information you gave us)

So in HBase every cell is stored along it's row key, family name,
qualifier and timestamp (plus length of each). Depending on how big
your keys are, it can grow your total dataset. So it's not just a
function of value sizes.
