Miklos Gergely commented on HIVE-19710:
---------------------------------------
I've tested it with mysql, and it works fine. Obviously the purpose of the for
update clause is lost, so in case someone is trying to create a catalog at the
same time there may be an issue. But as I see it was a bit overcautious, as the
only way to create a catalog is this, and it seems unlikely that someone is
running two instances of the program at the exact same moment.
