  So that means any user can revoke or give permissions to any user for any
table in the metastore?

I have read about roles, user privileges, group privileges etc.
But these roles can be created by any user for any database/table. I would
like to know if there is a specific 'administrator' for hive who can log on
with his credentials and is the only one entitled to create roles, grant
privileges etc.

Thank you.
