kirby zhou commented on RANGER-3683:
------------------------------------
If you enter plain-text password, the exception will happens, but nothing need
to do.
HiveClient.initConnection calls org.apache.ranger.plugin.util.PasswordUtils to
try to decrypt the password, if fails it then fallback to just use the password
as plain-text.
PasswordUtils.decrypt print the exeception log when the password is plain-text
(not encrypted).
So, it seems just you use a wrong username / password.
If you have more logs, please provide it.
