I have a NDB cluster with 4 mysql nodes and 2 management nodes. The current version is ndb 7.4.12 and mysql 5.6.31.
Trying to update, I have update the management nodes to the version ndb 7.5.5 and mysql to 5.7.17.
The error happens when I try to upgrade the mysql nodes (one by one).I changed the binaries and restart the mysql server, but trying to make a "mysql_upgrade" I receive this error:
