This is most likely caused by a git client misconfiguration; please make sure to:

1. check if your git client is configured with an email to sign commits git config --list | grep email
2. If not, set it up using git config --global user.email email@example.com
3. Make sure that the git commit email is configured in your GitHub account settings, see https://github.com/settings/emails

Just submitted my cla agreement.

Are these typical issues with the build or should I investigate this more?

No, those are unrelated. There are some flaky tests we're trying to track down.
