CDH upgrade 5.11.0 to 5.13.0 - Got Host Configuration Warning

[ Edited ]

Hi there 


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.


Thank you.
