Uhm...
Ok... I just did a quick Google search on Hadoop and Derby...
https://issues.apache.org/jira/browse/HADOOP-4133

Then there's this subproject called Hive... :-)
Oh and then there's this other subproject called Oozie... :-)

Now Cloudera and other support MySQL in the role of Derby aka Cloudscape aka JavaDB. 
Here's a link to a blog on setting up MySQL...

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