Huh? Sorry but HBase *DOES* support composite keys.
The OP's question is can you create a row key that is comprised of both 'student' and 'student_id'. I'm not going in to more detail because this sounds like a homework problem. Composite rowkey and composite index are two different things, yet still related because the row key has an implied index. Sent from a remote device. Please excuse any typos...
