Hadoop doesn't use derby. It does, however, use HSQLDB for its external DB I/O
and example components.

Hi,
AFAIK, HIVE will use the derby for storing the metadata.
I am not expert in HIVE, but i can give the some info.
HIVE will store the table and hdfs path mappings ralated information in Derby.
I think you can configure other DBs as well but by default Hive supports derby
