in this case we have to distinguish between 'give me family X' and 'give me
family X 0 length qualifier' which are in fact different queries and are both
representable in the standard Get Java API.
the java code does this by using a map of a map in the Get object:
Map<byte[], Set<byte[]>> familyMap;
where the key is the family, and the value is the set of qualifiers for
said family. If you want to get a family the code will use 'null' as the Set
value.
For the Avro API we don't have to do it in the same way, but we need to
know the difference between those queries. perhaps using AColumn 'family = foo,
qualifier=null' can be the 'give me the family' and 'family = foo, qualifier =
0 length bytes' can be the other?
