I started to do a rolling upgrade of 7.6.4 to 7.6.6.

I used this:
- https://dev.mysql.com/doc/refman/5.7/en/mysql-cluster-upgrade-downgrade.html
- https://dev.mysql.com/doc/refman/5.7/en/mysql-cluster-rolling-restart.html

And then replication from an InnoDB instance the NDB cluster failed:
Last_SQL_Error: Error 'Got error 763 'DDL is not supported with mixed data-node versions' from NDBCLUSTER' on query. Default database: 'db1'. Query: 't1'

I don't see that mentioned in the docs.

How to repeat:
Try to find if DDL is supported while doing a rolling restart upgrade.
