Butao Zhang commented on HIVE-29078:
------------------------------------
[~dengzh] Please check the standalone hms debug log file.
I can confirm that the connection to MySQL is ok, and this error does not
cause the HMS to fail to start.
Additionally, this error does not occur every time during startup, but it
appears relatively frequently when starting up.
