Hello，everyone
I am work on reading nifi's source code . it confuse me when i read the
class "AbstractPolicyBasedAuthorizer", I found there is no method to add a user
to an existing group. I noticed there is an "updateGroup" method ,which i don't
think can be used to add users to existing group, because it checks the input
group to make sure it didn't exist.
Am i right? can anyone help me, thanks alot !Best Regards YuNing
