Travis is failing, because the license plugin is expecting a header like this, as this is the first change of the year for this file :)

# Copyright 2017-2018 The Jaeger Authors

So, could you please run mvn license:format and update the PR? Or, if you prefer, just use the line above for all-in-one/jaeger-all-in-one-template.yml

@maximmold, I'm truly sorry, but your commit is still missing the "DCO". This is required in order for us to accept your contribution.

All it takes is to use the "sign-off" option in git, like:

git commit --signoff --amend

Please, do read the following to understand what DCO is and how it works: https://github.com/probot/dco#how-it-works
