Description:
If data nodes are not fully started and connected to mysqld then hidden ndb$ tables are visible in ndbinfo.

How to repeat:
start ndb_mgmd, ndbd, mysqld

$ mysql
mysql> use ndbinfo

enter before ndbd is fully started and connected to mysqld

mysql> show tables;

Suggested fix:
Hide hidden tables at all times.

This was fixed in NDB 8.0 prior to release, so no NDB 8.0 versions affected.

Closed.
