Hi everybody, I took more than expected but we finally published the blogpost about our migration to Bigtop 1.5: https://techblog.wikimedia.org/2021/05/07/upgrading-hadoop-in-just-one-day
I will also keep working, if you think it is worth it, to https://docs.google.com/document/d/1fI1mvbR1mFLV6ohU5cIEnU5hFvEE7EWnKYWOkF55jtE (I followed up to some comments made by Evans, sorry for the lag in answering!). Comments and suggestions are very welcome, the goal should be to eventually move the guide to the website or the wiki (or something similar). If anybody in the community has doubts/suggestions/questions/etc.. about moving to Bigtop I am available to answer any question! Now I hope to have some spare time to work on Jiras :P Thanks, Luca
