Description:
Hi,

According to the documentation for version 8 here: 
https://dev.mysql.com/doc/refman/8.0/en/mysql-cluster-config-example.html

Using the my.cnf in the example doesn't work for either ndbd or ndbmtd.

ndbd: [ERROR] unknown variable 'connectstring=ndb-mgmt0,ndb-mgmt1'.

 

How to repeat:
1. Copy my.cnf from https://dev.mysql.com/doc/refman/8.0/en/mysql-cluster-config-example.html to /etc/mysql/my.cnf

2. change the host names to suit my environment

3. Attempt to run either either ndbd or ndbmtd.

Suggested fix:
Change connect-string to ndb-connectstring where applicable.

This works for me with a recent 8.0.33 build.

Thanks, but this does not seem to be a bug.
