Description:
deleting non exiting row inside transaction breaks transaction

How to repeat:
look at CSC 25934 for the test case

Suggested fix:
n/a

Here is the simple test case:

-- The problem is with TEXT field. If we remove TEXT field everything works ok
DROP TABLE `t1`;
CREATE TABLE `t1` (
  `f1` int(11) NOT NULL DEFAULT -1,
  `f11` text,
  UNIQUE KEY `i1` (`f1`)
) ENGINE=ndbcluster DEFAULT CHARSET=utf8;

INSERT INTO `t1` VALUES (123,NULL);

DROP TABLE `t2`;
CREATE TABLE `t2` (
  `f1` int(11) NOT NULL DEFAULT -1,
  UNIQUE KEY `i2` (`f1`)
) ENGINE=ndbcluster DEFAULT CHARSET=utf8;

BEGIN; delete from t1 where f1=123; delete from t2 where f1=5; COMMIT;
