If you are writing a GenericUDF or serde and want to return struct
types there are object inspectors to build structs. The Java type
return is an Object[]. Hive expects that if the struct has 5 fields
the object array will have a length of 5.

Cool. Thanks :)
Also was just curious what do people generally use to write struct data in hive
tables? I see that there is a STRUCT function defined that takes parameters and
creates structs off them. Can we use a custom class as well?
Thanks again.

in your case hbase has a custom serde, the Deserializer interface is
what turns the value from the input format into something that hive
can understand. HBase support uses the user specified table property
columns.mapping as information for what it should parse out of the
hbase result.
