The username/password is needed because the user that issues calls against the '___protobuf_metadata' cache (registering marshallers) is required to have the admin permission in JDG. In the 8.12.x version of the translator, the ability to specify the username/password was needed because the metadata was retrieved before a user query was submitted. And this appears to occurs when the hotrod client is in a different host machine. was (Author: van.halbert): No issues when implementing.
