[ https://issues.jboss.org/browse/TEIID-4904?page=com.atlassian.jira.plugin... ] Van Halbert commented on TEIID-4904: ------------------------------------ No issues when implementing. 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. -- This message was sent by Atlassian JIRA (v7.2.3#72005)
