When using mysqldump to back up and restore schema information while using ndb_restore for restoring only the data, restoring to MySQL Cluster NDB 7.1.4 from an older version failed on tables having columns with default values. This was because versions of MySQL Cluster prior to MySQL Cluster NDB 7.1.4 did not have native support for default values.

In addition, the MySQL Server supports TIMESTAMP columns having dynamic default values, such as DEFAULT CURRENT_TIMESTAMP; however, the current implementation of NDB-native default values permits only a constant default value.

To fix this issue, the manner in which NDB treats TIMESTAMP columns is reverted to its pre-NDB-7.1.4 behavior (obtaining the default value from mysqld rather than NDBCLUSTER) except where a TIMESTAMP column uses a constant default, as in the case of a column declared as TIMESTAMP DEFAULT 0 or TIMESTAMP DEFAULT 20100607174832.
