Hi Sebastian, Thanks for bringing this up.
The ASF is rather explicit about category-x licenses [1] and LGPL is part of them; they are not allowed neither in the source nor in the convenience binary releases [2]. They can be present in the repo, used during the build, but must not be part of the release. Based on this, it seems that Hive is in violation of the ASF policy since there are releases which include the aforementioned file. I think the file should be excluded from the release artifacts or removed completely from the repo. Not sure what needs to be done (if anything) for the past releases.
