Doug Meil commented on HBASE-1989:
----------------------------------

Wow, this is from the way-back machine (2009).  But I still think it's a good idea from a
terminology standpoint to clear this up in the API

> Consider the classes HBaseAdmin and HColumnDescriptor.
> HColumnDescriptor is really referring to a "column family" and not a "column" (i.e.,
family:qualifer).
> Likewise, in HBaseAdmin there is a method called "addColumn" that takes an HColumnDescriptor
instance.
> I labeled this a bug in the sense that it produces conceptual confusion because there
is a big difference between a column and column-family in HBase and these terms should be
used consistently.  The code works, though.
