Description:
While trying to run a specific application with ndb cluster I got this "unknown error"
from ndbcluster:
 
mysql> SELECT DATE_FORMAT(day, '%Y%m%d') as date, DATE_FORMAT(day, '%d-%m-%Y') as
date_formatted FROM phpads_adstats GROUP BY day ORDER BY day DESC;
+----------+----------------+
| date     | date_formatted |
+----------+----------------+
| 20040927 | 27-09-2004     |
| 20040918 | 18-09-2004     |
| 20040917 | 17-09-2004     |
| 20040916 | 16-09-2004     |
| 20040915 | 15-09-2004     |
+----------+----------------+
5 rows in set (0.23 sec)
 
mysql> SELECT DATE_FORMAT(day, '%Y%m%d') as date, DATE_FORMAT(day, '%d-%m-%Y') as
date_formatted FROM phpads_adstats GROUP BY day ORDER BY day DESC LIMIT 7;
ERROR 1296 (HY000): Got error 1 'Unknown error code' from ndbcluster
mysql> 
 
As shown above, if I omit "LIMIT 7" at the end of the query I get results, when I use
LIMIT to narrow the returned rows I get this unknown error from ndbcluster. 

How to repeat:
CREATE TABLE `koko` (
  `views` int(11) NOT NULL default '0',
  `clicks` int(11) NOT NULL default '0',
  `day` date NOT NULL default '0000-00-00',
  `hour` tinyint(4) NOT NULL default '0',
  `bannerid` smallint(6) NOT NULL default '0',
  `zoneid` smallint(6) NOT NULL default '0',
  `source` varchar(50) NOT NULL default '',
  PRIMARY KEY  (`day`,`hour`,`bannerid`,`zoneid`,`source`),
  KEY `bannerid_day` (`bannerid`,`day`),
  KEY `zoneid` (`zoneid`)
) ENGINE=ndbcluster DEFAULT CHARSET=latin1;

INSERT INTO `koko` VALUES
(1,0,'2004-09-17',5,100,100,''),(1,0,'2004-09-18',7,100,100,''),(17,0,'2004-09-27',20,132,
100,''),(4,0,'2004-09-16',23,132,100,''),(86,0,'2004-09-18',7,196,196,''),(11,0,'2004-09-1
6',16,132,100,''),(140,0,'2004-09-18',0,100,164,''),(2,0,'2004-09-17',7,132,100,''),(846,0
,'2004-09-27',11,132,164,''),(1,0,'2004-09-18',8,132,100,''),(22,0,'2004-09-27',9,164,132,
''),(711,0,'2004-09-27',9,100,164,''),(11,0,'2004-09-18',0,196,132,''),(41,0,'2004-09-27',
15,196,132,''),(57,0,'2004-09-18',2,164,196,'');

SELECT DATE_FORMAT(day, '%Y%m%d') as date, DATE_FORMAT(day, '%d-%m-%Y') as date_formatted
FROM phpads_adstats GROUP BY day ORDER BY day DESC LIMIT 7;
