In case you are using git-svn and see the following error after running "git svn rebase" on a brach:
Author: [name] not defined in .git/authors.txt file just cd into the .git directory and add the user to the /authors.txt file where [name] is the apache user name. [name] = Full Name <[name]@apache.org> save file. run "git svn rebase" again.
