-------------------------------------------------------------
Thanks [~mohitsabharwal]!
Description is fixed, thanks for pointing out!
The "select current_user()" command will return the user provided by the
configured HiveAuthenticationProvider. For some cases it is the same as logged
in user, but some cases it provides the user that runs the hiveserver2 process.
The proposed patch adds a new udf which uses the sessionstate to get the
username. This way providing the identifier of the logged in user provided at
connection time. I think this is more consistent with the expected behavior for
relational databases, but do not want to change the original function, since
its' description explicitly states, that it will use the AuthenticationProvider.
I hope I was better at describing the problem now :)
Thanks,
Peter
