HBase book possible typo

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,
Akash A

Hi,
    I'm sorry. I should have been more clear. I was talkin about "HBase: The
Definitive Guide". This link i've pasted below

Once again sorry for the inconvenience caused

Cheers,

Hi there-

Can you point me to the specific section where you saw this?

http://hbase.apache.org/book.html

I don't see HColumnFamily in there.
