 * 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)
