When create your table, you specify the column families in the table (code
snippet from TestFromClientSide3.java):
HTableDescriptor htd = newHTableDescriptor(hTable.getTableDescriptor());
HColumnDescriptor hcd = new HColumnDescriptor(htd.getFamily(FAMILY));
htd.addFamily(hcd);
admin.createTable(htd);
When you insert data, you specify column along with data value.
Cheers
