HBase book possible typo

[Akash Ashok]

Hi,
     In the HBase book Architecture -> Storage -> Overview
     Its quoted that " The HRegionServer opens the region and creates a
corresponding HRegion object. When the HRegion is opened it sets up a
Storeinstance for each
* HColumnFamily* for every table as defined by the user beforehand."

Shouldn't it be HColumnDescriptor ? There's nothing called the HColumnFamily
right ?

Cheers,
