Bug #60484 Crash when renaming tables to other database if it contains BLOBs

Description:
If a table contains BLOB/TEXT, it cannot be moved to another database. Renaming within the same database is okay. If we attempt to move it to another database, the SQL node crashes and the table become unaccessible!

How to repeat:
shell> mysql test

mysql> create table t1 (a int primary key, b blob) engine ndb;
Query OK, 0 rows affected (1.47 sec)

mysql> rename table t1 to t2;
Query OK, 0 rows affected (0.74 sec)

mysql> create database test2;
Query OK, 1 row affected (0.10 sec)

mysql> rename table t2 to test2.t2;
ERROR 2013 (HY000): Lost connection to MySQL server during query

Suggested fix:
n/a

The table is unaccessible even after restart of the SQL node or the entire cluster.

BLOB table remains in the original table like below:

ndb_show_tables -c localhost:4000

pushed to 7.0.25 and 7.1.14

Documented bugfix in the NDB-7.0.25 and 7.1.14 changelogs as follows:

        Renaming a table having BLOB or TEXT columns (or both) to
        another database caused the SQL node to crash, and the table to
        become inaccessible afterwards.

Closed.
