Description:

Encountered a problem with 'LOCK TABLE'.

Given an NDB table named 'user':

mysql> describe user;
+--------------+------------------+------+-----+--------+--------------+
| Field        | Type             | Null | Key | Default|Extra         |
+--------------+------------------+------+-----+--------+--------------+
| user_id      | int(10) unsigned |      | PRI | NULL   |auto_increment|
| email        | varchar(255)     | YES  |     | NULL   |              |
| first_name   | varchar(64)      | YES  |     | NULL   |              |
| last_name    | varchar(64)      | YES  |     | NULL   |              |
| login        | varchar(255)     |      | MUL |        |              |
| mobile_phone | varchar(32)      | YES  |     | NULL   |              |
| password     | varchar(255)     |      |     |        |              |
| phone        | varchar(32)      | YES  |     | NULL   |              |
| hidden       | tinyint(1)       |      | MUL | 0      |              |
+--------------+------------------+------+-----+---------+-------------+

Consider the following:

        mysql> LOCK TABLES user WRITE;
        Query OK, 0 rows affected (0.00 sec)
         
        mysql> delete from user where login='jsacco';
        ERROR 1296 (HY000): Got error 208 '208' from ndbcluster

Now unlock the table and try once more:

        mysql> UNLOCK TABLES;
        Query OK, 0 rows affected (0.00 sec)
         
        mysql> delete from user where login='jsacco';
        Query OK, 1 row affected (0.02 sec)

How to repeat:
See above
