AFAIK, Fedora provides all of Arrow's dependencies except one: Re2 (kind of). For whatever reason, Re2 seems abandoned. There seems to be an automated release for every new version of Fedora, although the available package version is from 2016![1] I just opened a bug asking to update the version, now we need to find someone to look into it. Besides the above, you will probably also have trouble with Thrift, jemalloc, snappy, etc (not sure how critical they are as dependencies, the last two are probably critical). Personally, I have tried using the system Thrift, and failed miserably. On the other hand, I managed to use the system LLVM (for Gandiva) with a one line patch (merged in master). That said, as Kou pointed out, resolving ARROW-4383 probably will make this a lot easier. I hope this helps. Cheers, [1] https://apps.fedoraproject.org/packages/re2/changelog -- Suvayu Open source is the future. It sets us free.
