Test that each of the different SQL Column types that we support
can, in fact, be imported into HDFS. Test that the writable
that we expect to work, does.
This uses hsqldb as its test database.
This requires testing:
- That we can pull from the database into HDFS:
readFields(ResultSet), toString()
- That we can pull from mapper to reducer:
write(DataOutput), readFields(DataInput)
- And optionally, that we can push to the database:
write(PreparedStatement)
