The mapping between Git repositories and AccuRev streams is generally transparent to Gerrit Code Review users, but you should be aware of the added meaning of the Merged status when a change has been approved: in a mapped GitCentric environment, merged not only indicates that the changes have been merged in the repository, but they have also been successfully imported to the AccuRev stream. If you cannot get to the Merged status, you should check for error messages on the Gerrit Code Review page and troubleshoot any issues preventing the import.
