Subject Re: What is the safest way to enable authorization?
Date Thu, 09 May 2019 06:36:47 GMT

before changing the configuration from `AllowAllAuthorizer` to
`CassandraAuthorizer`, you need to grant enough permissions to the user
that allow all the accessed tables by that user. I think that should fix
the problem.
