[GitHub] flink issue #4397: [FLINK-7265] [FLINK-7266] Introduce FileSystemKind and Co...

    We've long experimented with the best way to do this in Hadoop, and I think we're converting on moving off any form of enum to some `hasFeature(String)` predicate. Why? Lets you handle a more of the obscure corner cases of blobstores, and have room to play in future versions. If it's a simple bool `isPosix()` all seems well, but in future you may even there want to consider a test for whether seek + write is supported, the FS is case sensititive, etc. Strings are probably going to turn out to be the best option
