I have updated our cluster from 5.11.0 to 5.13.0. I was able to finish the update work smoothly without any error.
But after updating, I got the following warning message on all hosts
"Host XX has upper-case characters in its name. Authentication through Kerberos will not work correctly in this case"
Kerberos is invalidated and is not used.
Host names are uppercase characters (ex. HOST_ABC), but warnings were not issued especially before 5.11.0.
There is no "suppress ..." button at the end of the message, so I can not set it non-display.
Please teach me how to turn the warnings off.
Changing the host name of all nodes will cause various problems, so I would like to avoid it.
